Zombies; they're fairly popular these days. For years they've been a staple in video games (see Resident Evil), are the basis of one of the hottest shows on television right now (The Walking Dead), and is even the center of a recently released romantic comedy in the US (Warm Bodies).
And, to perhaps capitalize on the current wave, a good chunk of this week's Xbox Live Markerplace savings are all centered around the undead as well.
Major Nelson has the entire rundown of what's available. At the top of the list are games: Zombie Driver HD, Zombie Apocalypse, Zombie Apocalypse: Never Die Alone, All Zombies Must Die!, and Zombie Wranglers.
Also, to augment your purchase of Zombie Apocalypse, you have the Zombie Apocalypse 2 Pure Pwnage Pack DLC. Plus, both the Call of Duty: Black Ops – Zombies Pic Pack and Call of Duty: Black Ops – Avatar Zombie Hat are there if you wish to show everyone your love for Call of Duty, zombies, and wasting money on game pics and avatar accessories.
Everything is half off the asking price and the sale last for one week.
