STORY
This is no training exercise.
This is the living nightmare we'd all feared.
It all started in Japan, 2022. An immense fleet of starships laid siege to an EDF base located in the rough city outskirts in the Kanto region.
This was an enemy humanity had never encountered, the Primers. Even worse, enormous insects attack the EDF base built even further underground. The EDF fights back.
Even more realistic battles
Armor will peel off where you shoot enemies, and their fluids will spill out onto buildings and floors, making you feel like you're truly on the EDF's battlefield.
4 EDF classes powered up like never before
As the player, take on missions with one of four classes. Finish missions to unlock new ones and advance the story. You can switch classes before missions as many times as you'd like.
