It seems like everybody's obsessed with some sort of undead creatures nowadays. Zombies, vampires, skeletons, republicans... They're popping up all over the place, and game makers are taking advantage of this left and right! Cases in point: most of the games below!

Pizza vs. Skeletons (universal) - Most of us have been craving a game that pits skeletons against pizza. Obviously, pizza is going to be the winner, which is why this crazy hodgepodge sort of arcade game puts you in control of a giant, customizable pizza. Skeletons rise from the soil every thousand years, but a doughy arch nemesis arises this time around, and it's your job to roll, jump, and crush the boney bad guys with your supreme skills. Not only that, but you'll participate in over 100 neat-o levels with dozens of themes, including skiing down long snowy slopes, finding and rescuing puppies, balancing, swimming, taking out skulls in a very Crush the Castle sort of manner, and even customize your pizza with all sorts of accessories. You're a Renaissance pizza, that's for sure. A very creative game that's worth its weight in laughs and sheer awesomeness. Pizza vs. Skeletons Free is also available.

ZiGGURAT (universal) - An arcade game of raw survival! Standing on a cloud-piercing mountain, it's you versus evil alien robot things who really want to be kind of this here hill! Armed with a single-shot gun, you must lob shots at the foes to keep them away from the pinnacle. Two control schemes let you customize how you play, but beyond that, it's up to your skill with this simple weapon to see how long you can survive. Bonus 16-bit visuals give it an extra epic feel!

Zombie Panic in Wonderland Plus (universal) - File this one under the "guilty pleasure" category. A mobile version of the Wii game, Zombie Panic lets you choose a character and defend yourself (while dealing massive amounts of destruction to the town around you) against zombie hordes, each more disgusting and crazy than the last. Tilt your iOS device to move and tap the screen to fire. Pick up ammo and new weapons while you fight for survival, and unlock new levels and characters from the store. It's a little light on content without an in-app purchase or two, but it's massive amounts of fun all the same.

Cavorite 2 (universal) - A sequel to the platform puzzle game released in 2011, Cavorite, and it looks and plays even better than the original! In the late 19th century, an anti-gravity substance known as cavorite was created. A scientist used it to travel to the moon, but the inhabitants didn't take kindly to his arrival and kidnapped him. He managed to escape only to crash moments later. The professor heads out immediately, in search of a new source of fuel. By pushing blocks and manipulating switches, make your way to the exit in each level. You can also spray objects with cavorite to give them anti-gravity properties, grabbing on to them for a little boost when needed.
