Telltale Games may have announced a release window for the third episode of their The Walking Dead series just a few hours ago, but now word has come out that they aren't the only ones developing games based on the ultra-popular zombie franchise. Activision just announced that they are working on a new FPS based on the property, one that will take players back to the very beginning of "Hell on Earth," as the teaser trailer below refers to it.

Check out the first trailer to get a sense of how the vibe that the new game will have. It will star two brothers who will have to cope with their own personal issues even as they battle through hoards of undead. Other than that, very little is known about the game, and in typical teaser trailer fashion, the short clips below show just enough to pique our interest.

Be sure to stay tuned to GameShampoo in the future for more information on this new The Walking Dead game.
