This is a first person shooter game, in which there are zombies infinitely spawning.

You can only take 5 hits from the zombie, then you are dead. Do not linger around too much because by the end many zombies will collect up, and you will have a lot of trouble. 

Kill zombies, to set a high score and a to beat your own high score.

PS: The difficulty of the game can be set in the options menu. If not selected, the default difficulty will be medium. Also, this is an updated(bug-free, hopefully) version of this game, with a sensitivity slider which can be adjusted according to your wish.
