PAX South was a great PAX for party games. Invisigun Heroes (opens in new tab), Western Press (opens in new tab), and most recently Ultimate Chicken Horse are some of the most promising local multiplayer games I've tried since the likes of Towerfall (opens in new tab) and Duck Game. In Ultimate Chicken Horse, you build levels with your friends, trying to make them just hard enough that you can beat them but they can't. Watch the video above to see how it works, and expect Ultimate Chicken Horse to release in March.
Sabotage your friends, and probably yourself, in Ultimate Chicken Horse
