SAS: Zombie Assault 3

In SAS: Zombie Assault 3, a fortified house comes under siege from the dead. Guard the rooms, move along the perimeter, and repair the window defenses before the horde breaks through. More weapons are available in this third game, and the fight spreads across five houses packed with larger zombie waves.

How to play?

Run between passages and place barricades where zombies enter. Upgrade each barrier from wood to metal, then to armored plating. Survive wave after wave, spending money on stronger guns as the pressure rises. By wave 30, zombie damage and aggression jump hard. Buy a bulletproof vest in the store, set up automatic machine guns inside the house, and blast any undead that get past the barricades.
