Telltale's take on The Walking Dead, a five-episode series of adventure games, has won the hearts (and eaten the brains) of pretty much everyone who's played it. Now the third episode is available on iOS devices, so even those without a PS3, Xbox 360, Windows PC, or Mac can get in on the story-driven zombie action.
Even if you already have it, it may be worth the extra investment just to be able to play on the go. The base app is $4.99, and an additional $14.99 gets you all five episodes (the first three right now and the final two when they're released on iOS).
Check out the game on the App Store and let us know what you think of the episodes so far.
