This main point of view shooter bridges the line between careful strategy and daring fighting. In the game, when people move forward, time moves forward. The health bar doesn't regenerate; the ammo doesn't drop haphazardly. The enemy is more numerous than you, and the firepower is stronger than you; and you are only alone, you have to pick up the weapons of the dead enemy, shoot, slash, and walk through the dense bullets moving at a low speed, making it difficult to move forward.
