Shoot and kill zombies as you try to survive as many waves as possible! You gain experience points for each kill and earn money for each completed wave. After you die, you can use your skill points to upgrade your character and spend your money on new weapons. Every 10 waves marks a checkpoint, which means you can start the game from that wave if you die.
