Survival Crisis Z.
A freeware zombie game.
Made by the person who made, " I mad3 a gaem with zombies in it ", It was one of his starting projects. It turned out really well! Quite scary as well, with it sometimes turning night. The creator's newest game is " The Dishwasher : Vampire Smile " which is what I saw Tom had!
The game doesn't like explaining itself from the start, so there is always the problem of Tom quitting because he finds the controls suck and he ends up deader than dead because he tried to take over the first safehouse he ran into.
The Controls all suck dick forever, You get Relative, Absolute, or the good way.
Relative is turn-and-walk tank, Absolute makes you move where you press the keys, but you'll have a hard time aiming without getting closer to your enemy.
So select Absolute + Mouse, but Ohno, you have to use the Arrow keys to move and CTRL to shoot! So redefine it to W,A,S,D. Set Inventory to Space.
Read the shit out of the Readme, and I suggest Doctor for your job, he heals automatically over time.
