We would suggest the charming zombie-killing game Red Vs. Dead to you. Before they infect the entire city, it is your goal to exterminate all of the zombies that are attempting to attack you. You will suffer health damage up to the point of failure, though, if you allow them to touch you. Jump to evade their assault while reloading your weapon so you can engage in combat at any time. Additionally, bombs can be used to eliminate a significant portion of your adversaries in a single attack. Wishing you luck on your mission!
