Overkill is finally done revealing all four playable characters in the developer's upcoming The Walking Dead co-op shooter.

Overkill's The Walking Dead has been a bit of mysterious game thus far. Outside of vague allusions about the world and gameplay, we practically don't know anything about the game.

Overkill pitched it as a four-player co-op shooter, with four heroes from different backgrounds coming together to survive the zombie apocalypse. So far, we've see trailers for Grant, Maya, and Aidan.

Today's trailer gives us a look at a bit of the backstory for Heather, the fourth and final lead. Like all previous character introductions, this one is strictly CG-only.

Hopefully, we'll be able to learn some concrete details about the game at E3 next week. Catch the trailer below, via IGN.
