Natural Calamity is the fourty-second offline mission and the fourty-fifth online mission in Earth Defense Force 2025 and the fourty-fourth offline mission and the fourty-seventh online mission in Earth Defense Force 4.1: The Shadow of New Despair.
Objective[]
Both Versions: Engage the Ravagers' flying drones that have entered the city.
Storyline[]
HQ start the mission by telling that the Ravagers' drones are coming and Storm Team can already see them flying between the two largest skyscrapers in front of them.
While they are fighting, Ranger-7 can be heard over the radio saying that they can see flying hexagon shaped objects. Then another soldier comments that it's a huge army to which Ranger-7 replies that they aren't just an army and the sky is pitch black.
After a while the objects also appear over Storm Team's position. Ranger-21 then reports that they are covering the sky, to which HQ intelligently asks whether he meant that they are covering the sky. The Tactics Officer then clarifies by saying that the flying objects are connecting to build a wall then HQ, still not on top of his game, asks whether she meant that they are building a wall. The TO then patiently explains that the hexagons have been appearing around the world and started covering the Earth in a wall. HQ then questions what the ravagers are planning and seems to be finally catching on what the soldiers meant by "swallowing the Earth".
The TO then reports the appearance of a new type of Flying Vehicle, a bit late since they were here since the previous mission. Soon enough one of the hatches on the hexagons open and the new drones start to pour out and HQ orders to destroy them. Then some soldiers who probably didn't hear what the TO said shout that they flying vehicles and that it's a new type.
Ohara then starts another monologue about how the Ravagers' force is bigger than they though. Then he again shows how little he knows about physics (or any science, really) by stating that the Ravagers have weapons that are equivalent to a planet's mass. While it's unknown how big the hexagons' mass is and it could be possible that he's right, the fact that they can cover the Earth means that they have larger surface area and not mass. HQ asks for a counter measure to which he exclaims that it's impossible and they are like gods. HQ finally gets tired of his rambling and only says "I guess so".
When Storm Team finally finishes off the flyers, five more hatches open and HQ warns that more Flying Vehicles are coming. He then gives the hexagons the designation "Earth Eaters".
Ohara then makes the important discovery that the Earth Eaters are dropping Flying Vehicles.
When all of the Flying Vehicles are destroyed the mission ends.

Strategy[]
4.1[]
The only enemies on this mission are flyers so bring weapons with good accuracy and/or missile launchers that can shoot multiple targets. You might also consider bringing a high damage weapon against the Earth Eater Hangars. Air Raiders should forgo the air support and artillery and instead bring ground support equipment preferably turrets.
This mission is one of the few that is set on the City 2 map, where the overpass above the park isn't completely destroyed. It covers a large amount of area and grants a great defense against flying enemies and should be used.
The second wave spawns a large amount of enemies (34) from one hangar. It takes time for all of them to spawn so if you brought a weapon with high enough damage then it's possible to destroy the hatch and prevent many of them from being deployed.
The last wave is also dropped from the hangars, this time from five of them. The individual hatches drop less vehicles (10), so it's not as effective as in the second wave, but destroying the hangars is still a good idea.
