Recently release Moribund offers local multiplayer mayhem for 2 to 4 players in a post apocalyptic setting. Invite your friends over for a friendly fight to the death. (This game looks pretty bloody so you may want to keep that in mind - everyone has a different tolerance to gore and mine is pretty low.)
Moribund is on special offer (15% off) ending on 23th March 2017. Available on Steam.
