• 3 difficulties: Easy, Normal and Hard

★ THE HORDE
• 13 kinds of zombie: walkers, runners, riot cops, bloaters, screamers, burning zombies, dogs, tanks and more
• 13 monsters that leap, spit acid, burrow, swarm — or only exist inside your flashlight beam
• 6 bosses — the Butcher, the Broodmother, the Lasher, the Warden, the Siren and the Furnace — each with its own way to bring it down

★ GEAR UP
• 11 weapons: pistol, SMG, assault rifle, shotgun, marksman rifle, machine gun, flamethrower, grenade launcher, minigun, railgun and machete
