You play as the zombies and try to infect as many humans as possible. It's F2P but you really don't need any microtransaction purchases to enjoy the game.
I'm not sure what kind of game Zombie Infection is, but Infectonator sounds like it could be similar. It was a lot of fun for me so check it out if you don't find a way to play the games you want.
The is also Infectionator World Domination, Infectionator Christmas Addition, and Infectionator Hot Chase. Oh, and the app. Fun game.
