Fortress Frenzy is is the fiftieth offline mission in Earth Defense Force 4.1: The Shadow of New Despair.


Objective[]

4.1: The infamous quadruped fortress took the city by surprise, with many citizens unable to evacuate. Many were lost. We'll engage the enemy on the spot and give the remaining civilians time to escape. Just remember: Only ground troops stand between that fortress and the lives of our people, since our Air Forces are heavily depleted. This will be a decisive battle. We must destroy the quadruped fortress! Help buy some time.

3rd Dropped from the Quadruped Fortress after the second wave is defeated. Crimson Ant
4th Dropped from the Quadruped Fortress after the second wave is defeated. Hectors

Strategy[]

4.1[]

Bring a high-damage weapon with enough range to reach the Quadruped Fortress and to deal with the final wave of Hectors; and a weapon that has excellent crowd-control capability. The Quadruped Fortress does not need to be destroyed in this mission, despite what the mission description says. Start the mission by taking command of the 2 nearby Ranger teams; if you are fast you can take both teams before the first wave is dropped. Shoot the weapons on the Quadruped Fortress whenever you have extra time, they can be destroyed, and they can chew you up very fast. Once the ants are on you, you can focus entirely on them, trying to keep as many allies alive as you can.

After the first wave is defeated you can chase after the Quadruped Fortress and the newly spawned Ranger team should be nearby to take command of. Destroy all Flying Drones and begin moving back toward the spawn area to take command of the newly spawned Fencer team. You should now have a large amount of allies gathered and you will probably need them, the 3rd wave is a quite large wave of Crimson Ants. Once you have dealt with all the ants, the Quadruped Fortress may have already begun dropping Hectors. Destroy them. The mission is complete once all enemies other than the Quadruped Fortress are defeated.
