What the fuck

From a first-person perspective, the player moves through a narrow, debris-strewn alleyway between wooden buildings, aiming a rifle at a large, crab-like creature labeled "ALPHA HERMIT CRAB" that emerges from the smoke and fire ahead. The player fires at the creature, which retaliates with a powerful attack, causing the screen to shake and blood splatters to appear as the player's health decreases.
