Move with WASD, look around with the mouse, click to interact or shoot. Press F to interact with doors, drawers, and items. Use Q or E to access the security camera system from designated terminals. Press R to reload your weapon.
On mobile, on-screen joysticks handle movement and look, with action buttons. Complete each floor's objectives while managing ammo and avoiding unnecessary combat.
Use the Cameras Constantly - The security camera system shows zombie positions before you walk into them; treating cameras as your scout saves runs.
Reload Behind Cover - Reload animations leave you vulnerable; never reload in the middle of a corridor where a zombie could close on you.
Learn the Floor Layouts - Each hospital wing has multiple paths between objectives; knowing alternate routes lets you avoid blocked or contaminated areas. Save Heavy Weapons for Bosses - The boss encounters are where firepower matters; using shotguns on basic shamblers wastes resources.
Don't Rush Objectives - The game rewards careful exploration; sprinting through floors causes you to miss healing items, ammo, and safe rooms.
