collect all the vials to eliminate the virus - WASD to move - R to open reload menu, click shells to load into gun, you can't move while reloading - SPACE to sprint - left click to fire, only two shells in the chamber at a time - zombies spawn more often at night and can jump over walls when the time comes. they spawn more often the longer you play, hence the danger level - health stations are marked on the map - don't touch the lava, water makes you slower but doesn't affect the zombies, beware good luck
