Here's what I'm wondering: Have we officially hit the zombie-meme overload point? I decided to find out--in between bouts of and (both great titles)--by playing the latest dead-centric games roaming stores.

In a quick search on the iPhone App Store, I count at least 50 offerings that have something to do with zombies. Seriously. Go see for yourself. How many of those games are actually good? That's a whole other question.

7 Days Apocalypse (iPhone)Last week, at the height of the mainstream-media panic attack, came out, putting you in the position of slaying victims of the "S-Virus" (S...swine...get it?). I don't know whether that was intentional, but my hat's off to you, sirs, for jumping on the panic wagon and poking fun at it. As for the game itself, it's a run-and-shoot quick hit like iDracula--use one thumb to control where you move, and use the other to aim the shot--that has you gunning down countless waves of foes.

Two ways 7 Days stands out: A "Story" mode throws a couple of curveball scenarios at you (escort and defend a fleeing scientist, for instance), and an over-the-shoulder camera mode makes for some interesting screenshots...but also makes the game tough to play. Given an update spit shine, this game could be fun. For now, it's a good work in progress.
