Earth Defense Force 6 (地球防衛軍6 Chikyū Bōeigun 6) is the sixth main entry in the Earth Defense Force series and the eleventh overall counting the spinoff games.

The game is currently available in Japan on PlayStation 4 and PlayStation 5. A worldwide release has been announced for Spring 2024 for both the two PlayStation systems and Windows PC, with the latter to be featured on both the Steam and Epic Game Store platforms. It has broken sales records for the series, selling over 300,000 copies in its opening week alone.

Plot[]

EDF 6 is a direct sequel to Earth Defense Force 5, picking up three years after that game left off, in 2025.

After the Nameless was defeated, the remaining motherships collected its body and retreated back into space, abandoning the remaining on the ground. The EDF spends the next 3 years eliminating the remaining alien forces and trying to rebuild society. A tough feat considering the Aliens had manage to kill 90% of the Earths population.

3 years later however, they returned.

The story starts with Storm 1 being relocated to base 251 where he assists the local soldiers in clearing out what is left of the monsters. However, A giant ring-like spaceship appeared from the sky and seemed to have created a portal from which it was presumed that the aliens had simply evacuated the last of their soldiers. However, the next morning, the entire world was covered in flower like terraforming structures and was swarming with android machines. However this all seemed natural to all but 2 characters. Storm 1 and a weapon researcher named The Professor.

The 2 along with the rest of the soldiers launch an assault on the Ring and managed to damage it, causing it to self destruct. However, afterwards, Storm 1 suddenly finds himself back in the past, his first mission as part of EDF (EDF 5 mission 13, which is also EDF 6 mission 13). However from this point, things start to change. The first thing Storm 1 hears is the Major communicating with the Intelligence Division on how they have already lost 30% of their forces (20% in EDF 5) afterwards, the teleportation ships start deploying Aggressive Alien Species γ, a creature that wasn't deployed this early in the invasion in the previous iteration. The Intelligence Division also states that suddenly a whole new 20 ships of a completely different make suddenly appeared in the world at the same time that Storm 1 returned to the past.

From that point on more changes start to occur. The more elite units are being deployed much sooner, more bases are destroyed during the initial attack and new units are being deployed.

The Alaska base, that housed the 3 submarine carriers from EDF 5, was immediately bombed during the start of the invasion, preventing the carriers from being deployed with all their weapons. At the first mission in Europe, where the colonists were first deployed in EDF5, also saw the immediate deployment of the type 2 drones and the android monsters that were first seen in the future and from this point on, the teleportation ships no longer stay in one place in order to prevent from being shot down. During the second mission in which colonists were deployed. Armored colonists from EDF 5 DLC 1 also appear.

Eventually, The Professor manages to contact Storm 1 and tells him that he also retained his memories from the future and has sent him some weapons from the future in order to deal with the growing Alien threat. These new weapons prove to counter most but not all of the increase in the Alien's ability to commit war. To resolve this, The Professor approaches the Chief Commander with all his knowledge of the future but was promptly dismissed as a lunatic and sent to an insane asylum. Meanwhile the Nameless, with his subordinates giving him knowledge from the future, hides his ship on the far side of the moon and sends more units after Storm team. Resulting in the death of all but Storm 1. Afterwards the war continues as a hard fought battle.

5 years later (EDF 5 mission 1-110 takes places over a 2 year time period) , The Professor and Storm 1 Reunite at base 251. But before they could talk, base 251 is attacked by android monsters. Storm 1 defeats them and the next day the group is being let outside the base, right where they see the Ring descending. More alien ships go into the portal and back into the past. The next day, Storm 1 and the Professor wake up in an abandoned underground mall, with the aliens having now fully over run the earth. They go above ground and find the earth swarmed by a new species of aliens called Kruul. They are giant octopus with guns and shields. The duo once again make toward the ring and cause another incident.

The went back in time and landed in the exact same spot (EDF 5 mission 13). Only this time, the casualties are already at 40% compared to 20% and the aliens had managed to send back over a hundred ships compared to 20. The Professor once again makes contact and sends him a new package of weapons to Storm 1. Now being in possession of weapons a full 10 years ahead in research, Storm 1 starts being hailed as a hero by most of the EDF and rally behind him. With him leading the charge at every major engagement and the rest of EDF mindlessly charging in behind him, they were able to counter most but not all of the alien's ability to commit war. This time The Professor tries to get some credibility by pre-emptively releasing all the weaknesses of the aliens he had encountered in the future but had not yet been deployed in the past. The information was well received and The Professor once again approaches the Chief Commander but is once again dismissed as a lunatic and is once again send to an insane Asylum.

The EDF continues to win most of the major engagements but the extra manpower allows the aliens to grind the EDF down and eventually kill all of storm team except for storm 1. This forces the EDF on the back foot for the next 3 years but the remaining soldiers continue to give a stiff resistance.

3 years later and the duo once again meet in base 251. But they are once again attacked by aliens in the base. They repel them once more and once more they see the Ring descending. But this time however, he reveals some information. He had done some experiments and it has been revealed that the aliens had already used the time travel device 5 times before he and Storm 1 did. He also says that it explain the attack on the base 228 in EDF5. The aliens had no way of knowing where all of humanity kept all their nuclear silos but still managed to destroy most of them in a single hit. His answer was simple, after each attempt to take over the planet, successful or not, they send someone back with all the intel on how the previous war went and then they adjust the strategy accordingly until they have achieved a perfect victory.

However, he then immediately comforts Storm 1, saying that they can pull the exact same trick. Since their attack destroys the Ring, the aliens in the past will have no way of knowing the attack happened at all, as since the Ring is destroyed, they have no means of communicating with the past. However, as the duo approach the Ring, The Professor is immediately proven wrong. This time the Ring activated and instead of ships going into it, giant metallic tentacles with cannons appear out of it. Storm 1 manages to destroy them regardless and both he and The Professor return to the past regardless.

This time however, they arrive at EDF mission 5, 5 months earlier than usual. Storm 1 immediately uses his knowledge from the future to prevent a squad of tanks from being crushed by the first teleportation anchor, destroy the main gun of a mothership and destroy the first teleportation ship right from the beginning. This in turn causes the war to turn into the EDF's favor even more so than EDF 5. To counter this, the Aliens spend all their time on introducing just 1 unit, the Scylla. Unlike all other enemies, the aliens deployed them directly into the ocean and use them to attack the EDF's navy and coastal cities and very surprisingly, spread pollution (in contrast to EDF 5, the insects main goal is to remove pollution). At this point in time, the war remains even.

However, this time around, the aliens had the EDF's strategy fully memorized. Firstly, it allowed them to intercept the railgun reinforcements from EDF 5 mission 40 and in turn make that battle a win for the aliens. After several more battles like this, The Professor reaches out to the Intelligence Division but is once again dismissed as a lunatic. But, this time however, the information is picked up by Storm 1's Communication Officer (The egg shaped ship lunatic from EDF 5) and she decides to take it seriously. She reads the file and finds an alien attack planned for tomorrow and sends Storm 1 to intercept. And as the information was proven to be true, the intelligence division was forced to take The Professor seriously.

The next problem became the Siren, a monster first introduced in the second loop. This monster however has the ability to deploy the Scylla. To this, the intelligence division orchestrates a plan to kill the monster. They had managed to figure out that Siren needs to hibernate after every battle. So they planned on hitting Siren with an orbital laser the moment it went to sleep, to the objection of The Professor. The Intelligence Division ignored this however and went through with the plan. This in turn caused Siren to take its Super Saiyan form, Glaucus.

The Professor states that the only thing capable of killing Glaucus are cruise missiles that can only be fired by one of the Submarine Carriers and for once The Intelligence division listens to The Professor. The Professor convinces the Intelligence Division to let you escort the missiles to the dock where one of the Submarine Carriers is awaiting repairs, only for a mothership to be waiting for them. Storm 1 manages to defeat the mothership while the repairs are completed and the missiles are loaded onto the Submarine Carrier. The Submarine Carrier then manages to track down Glaucus and while Storm 1 keeps it occupied, the missiles manage to de-transform Glaucus back into Siren, which allowed Storm 1 to kill it.

After this battle, it was revealed that with the death of Siren, the aliens lost the ability to deploy Scylla and the aliens were left with only a little more combat power than what they had in EDF 5. With this success, The Professor essentially gains full control over the EDF. Firstly he massively increases the number of EDF soldiers and secondly he mass produces the weapons he had invented during EDF 7 and has them become standard issue. Afterwards, he orders a full scale assault on every Alien hardpoint on Earth, with Storm 1 leading the charge. After the battle however, with many casualties on both sides, he reveals that the attack was nothing but a diversion. As it allowed them to sneak attack the Nameless on the far side of the moon with every nuke they still had left, successfully killing him and forcing the remaining motherships to retreat while the vast majority of humanity was still functioning.

3 years into the future, humanity has managed to fully rebuild and fortify itself for the next round of aliens planning to make a visit. Storm 1 and The Professor return to base 251 almost out of instinct until they are pulled out the base and made to participate in a parade. A parade that was interrupted by the first wave of aliens. While Storm 1 is fighting the Aliens, The Professor reveals the next parts of his research. He had done tests on all the aliens that he had found and shockingly. Not only the giant insects but even the Colonists were proven to be 100% Terrestrial. Based on the data. He concludes that all the monsters were from at least one hundred thousand years in the future after some sort of incident had rendered humanity extinct. Based on his results, the end of humanity was brought on by over-pollution.

But the General and the Intelligence Division question the results. Why would an alien race a hundred thousand years from the future want to pick a fight with humanity if humanity is already dead in their timeline. Or better yet, why didn't they just jump even further into the past back when humanity was still in the stone age. But that conversation is interrupted by the arrival of the Ring. Despite the best efforts of the EDF, several ships still manage to sneak into the Ring and the next morning Storm 1 and The Professor still find themselves in the underground mall. But before they travel towards the surface, he announces his latest discovery, the bacteria found in the Kruul matches that of what they had pulled from soil samples on Mars. Proving that the aliens are actually Martians.

They continue on as they normally are at this point in time. However, when they get above ground, they are confronted by the Kraken and are forced back underground. They are forced to continue the rest of the journey underground until they reach the Ring. This time they find it even more heavily fortified than prior. Forcing them to realize that the Martians are on to them and that this just might be the last time they travel to the past.

The duo arrives in past prior to EDF 5 Mission 1. Storm 1 takes this opportunity to buy a gun and return to base 228 as in the original timeline. From there, he went on to save the Corporal who showed him around the base and since he already had a gun, the Sergeant didn't need to waste time teaching him how to use a gun. This in turn allowed him to save one of the Mechs before it was destroyed by the ants, which in turn allowed Storm 1 to pre-emptively save Barga, which in turn allowed him to save base 228 from falling anchors this time. This in turn allowed Storm 1 to kill Erginus the first time it appeared. This in turn gave The Professor extra credibility in being from the future and he manages to convince the Chief Commander to listen to him.

Meanwhile, the Martians put in extra effort in the invasion this time around so that even with the Professor in full control of the EDF, the fight is still a hard back and forth. The Professor has a theory regarding the Martians. The reason they never traveled further into the past is because there is something they needed to have happened in the past in order to prevent a time paradox.

While the battle was continuing however, the EDF had managed to track down Mothership 11 on earth. The nuclear attack on the moon in EDF 8 had forced the Martians to keep moving the Mothership in earth's atmosphere, the only place the EDF wouldn't nuke. Storm 1 had managed to find it, however it immediately made its escape while abandoning its garrison. This happened several times until Mothership 11's garrison was instantly destroyed by a squad of requiem cannons, forcing it to turn itself into the Egg Shaped Ship. However, when it was destroyed, it was revealed that The Nameless wasn't aboard the ship. This time around, the Martians still continued their assault on humanity, albeit disorganized. Luckily, The Professor had already taken control of the EDF and begun mass producing even more advanced weapons for the next 3 years. This in turn allowed them to force the Martians back.

After The Professor and Storm Team reunite in base 251 after 3 years, The Professor reveals what the rest of the research division had discovered. The reason for the Primers attack was because of their own temporal intervention. After the Primers had advanced their own civilization far enough, they paid a visit to earth and discovered evidence of a previous civilization. They created a time machine to observe earth and traveled back in time to a point where there ships wouldn't be detected. However, during the first travel, an accident occurred and one of the ships crashed several thousands of years earlier. This in turn caused Humanity to advance much faster then previously anticipated and their stealth ships were immediately detected and attacked. From this point, they couldn't further interfere with the past as they wouldn't be able to undo what they had already done without causing a time paradox.

But now that the Primers are on the back foot a second time, they send every last insect and monster they have to delay the EDF long enough for the time ships to go through the Ring unobstructed. However, this time, the future remained unchanged. When the time ships traveled to the past, they ended up teleporting to a battle where Storm 1 was present. This allowed him to destroy some of the time ships without them being able to use their retreat ability and taking away part of the Primer's ability to travel through time and the majority of their special forces. This in turn leaves the whole scale of the war largely unaffected and the future continues to occur unchallenged.

5 years later, the time ships are the only ships the Primers have left and they can no longer return to the past from this point as it would create a time paradox. So when the Ring arrives a large army is mobilized to attack the Ring. However, the Primers expected the attack and everyone but Storm Team was wiped out. Storm team continued on anyway and managed to destroy the Ring without causing another temporal incident. However, after the destruction of the Ring, another portal opens in the sky and a gigantic metal snake appears out of it. The Professor states that time is on the Primer's side, so they could just spend a couple centuries to develop some new technology and then simply send it to the past.

So to counter this, he nukes mars and makes the environment so desolate that nothing could ever evolve on the planet. However, since the Primers were instrumental in the development of humanity, humanity could never kill the Primers before they were born as it would cause a time paradox. After as such, space itself begins to warp and every EDF and Primer creature still on earth gets pulled to the same location as if the laws of time and space decree that the matter is to be settled here. The fight continues on and Storm 1 manages to destroy the head of the snake, revealing the head of The Nameless. The fight continues on and Storm 1 is victorious over The Nameless. After the victory of which, the Communication's Officer confesses her feelings for Storm 1.

Soldier Classes[]

All four classes from EDF 5 (Ranger, Wing Diver, Air Raider and Fencer) return in this game, with some alterations.

The Ranger and Wing Diver now have a dedicated "backpack" equipment slot for certain throwable items: both classes get their hand grenades shifted to this slot. The Ranger also now equips Impulse mines and C Bombs to the backpack slot along with his new stolen-from-the-Air Raider ZE-GUNs, while some of the Wing Diver's orb weapons also end up here. All thrown devices have had their controls altered, being thrown with a fixed amount of force like the vehicle summons in the previous game instead of having a variable aim line, though the throw distance can still be controlled to a degree by aiming the camera vertically.

The Ranger has also gained the ability to mantle over low obstacles that cannot be destroyed by his roll, and has had "super armor" frames added to his dodge roll. For the Wing Diver the news is not quite as rosy, as her air-dash moves have been made less powerful: there is a longer delay between boosts, as well as a roughly 50% increase in the energy cost of boosting. Both classes now have some weapons with a new mechanic related to mid-magazine reloads, decreasing the reload time for the Ranger and the energy consumption for the Wing Diver based on how much ammunition is still in the weapon.

The Air Raider also gains a "backpack" slot, but his hosts a more substantial collection of devices including his support posts, forcefields, decoys and exploding Roombas. A new set of strikes using a series of small drones that follow the Air Raider around have been added: contrary to many pre-release rumors, these strikes are an addition to conventional ones rather than a replacement for them. In addition, unlike the regular strikes, all drone-based strikes can be used in underground maps: related to this, the equip screen will now highlight any selected weapons the Air Raider cannot use in the current mission in red, in the same manner as weapons that exceeded online level limits in previous games. The previously extremely limited Suppress Guns have had their magazine size increase from 1 or 2 shots to 6 or 12 and all types have received a range buff, making them distinctly more serviceable as actual weapons. His sentry guns have been shifted over to the Ranger class.

The Fencer now defaults to having two boosts with any type of booster equipment instead of one, providing him mobility even with no support equipment. However, his jump boosts have been weakened somewhat since the previous game. Like the Ranger, he can now mantle over obstacles he cannot destroy, though this requires a boost in his case and the animation is slower. His weapons with spin-up times have been altered: rather than having to wait for the whole spin-up time before the weapon fires at all, these weapons now start firing immediately but their rate of fire gradually increases up to their proper rate during the spin-up time.

DLC[]

As usual, a number of low-level DLC weapon and equipment packs were available at release, including new Decoys bearing the licensed likenesses of a number of Hololive characters. A Season Pass was also available, which includes all mission packs as well as all DLC which was not a pre-order bonus or store-exclusive promotional item.
