Zombie Hunter

Zombie Hunter is a first-person shooter in which the player fights against zombies. In each d level, the player needs to defeat a fixed number of enemies. Money is earned for every kill and every rescued citizen (the player just needs to stand besides them and hold a button for a few seconds). The money is instantly deducted when reloading the gun. It does not matter how many bullets are left in the clip, the amount is always the same (but differs from gun to gun).

Sometimes the player will stumble on extras to pick up (rifle scope, double sized clip, revolver or extra money). Except for the money, only one extra can be used at a time and will vanish when the current level ends. Every few levels a new gun is rewarded, but the zombies also receive more hit points. The game is over when the player dies from too many zombie hits. The backstory is that scientists created a virus which causes every infected human to become a zombie.
