HISTORY This is not an exercise. It's a living nightmare that we all feared. It all started in Japan in 2022. A huge fleet of spacecraft has besieged the EDF base located on the outskirts of Kanto. It was an enemy that humanity had never encountered before, the Primers. To make matters worse, huge insects attack the EDF base built even deeper underground. EDF repels the attack. Even more realistic battles Armor will fall off where you shoot enemies, and their fluids will splash onto buildings and floors, making you feel like you're on a real EDF battlefield. 4 EDF classes enhanced like never before As a player, take on missions in one of four classes.
