Your hero in Undead Corridor must control the corridor to prevent zombies from breaking through to the premises where people are hiding. Move the hero along the corridor and destroy the undead that you encounter. The fastest defeat occurs when hit in the head, but there will be zombies in helmets, which will make it difficult to kill. You'll have to spend more ammo shooting at the torso. Some zombies are very fast, they are very dangerous so you will need a quick reaction. For each wave of attacks repelled, receive a reward. Spend money on changing weapons to more effective ones in Undead Corridor.
