Tonight I played All Zombies Must Die!
It's a top-down adventure / brawler in which the main character finds himself in the middle of a zombie apocalypse and thinks it's pretty cool. The gameplay pretty much consists of slaughtering your way across an area, using shotguns, flaming torches, cricket bats, etc. to kill various kinds of zombies.

As you progress you will proceed through the story, unlock additional characters and weapons, and level up those characters. The writing is funny as this is a parody of the zombie genre, and the main character occasionally breaks the fourth wall. The game controls fairly well and the key mappings are pretty logical.
