All Zombies Must Die!, the new co-op zombie shooter from doublesix, hasn't been getting enough attention. It will release this year, after all, but just barely: look for it on PlayStation Network starting December 27 (January 4 in Europe) and on Xbox Live Arcade December 28.
Undead fatigue is at an all-time high, so I can see why this game might not immediately seem noteworthy. The zombie slaying is solid enough, and if you are one to get pulled in by XP pop-ups, you'll soon find yourself wanting to play one more quest. And then another. Oh, who needs sleep.
Also, there's crafting -- we all know how that ends.
