The fourth and final playable hero in Overill's The Walking Dead is Heather, a kindergarten teacher turned hardened survivor who's introduced in yet another deeply unhappy trailer that's also somehow even more brutal than the previous three. 

It's interesting (and well-established in the Walking Dead world) that the most dangerous threat to survivors isn't the hordes of undead, but other survivors: Fellow humans who won't think twice about killing you to take your stuff. I had actually hoped that the encounter seen in the trailer would end with friends made, or at least a civil exchange of goods, but deep down I knew it was never going to happen: The Walking Dead is not The Talking It Out, after all. I didn't expect its in-your-face savagery, though. It's fine, I get it—the end of the world is a tough place—but I hope that the level of violence seen in the trailer is given some context within the game, rather than just tossed around now and then for shock value.
