5. Zombies At My Neighbours!
Let's go old school for a second, with this awesomely animated love letter to B-grade horror films. This is legit one of the hardest games I've ever played (in fact I don't think I've ever got past Level 8!) and the whole thing is played for laughs more than anything. Filled with all sorts of goofy monsters like shambling zombies, madmen with chainsaws and 20-foot-tall babies with toxic milk bottles, you're tasked with rescuing your neighbours from these monsters using your trusty holy-water-filled pistol. What's not to love? Zombies Ate My Neighbours was originally released on the Mega Drive and SNES back in the day, but is now available on Wii or from your neighbourhood ROM dealer.
