Don't Starve x TF2
*Murasmus is fed up with Soldier and his nonsense. So, he consults one of his other books (not Bominomicon) and opens a portal into a random dimension. Said random dimension just so happens to be the nightmarish land of Constant. There the Mercs run into the Survivors and learn 1) there is no way home, not from their side anyway; 2) how to survive in a world where everything, including you own insanity wants to kill you; 3) the rules of nature and physics and plain common sense are thrown out the window so don't rely on them to help keep you alive; and 4) how not to starve. At least the mercs are used to insanity and dying.
*The survivors finally manage to make it out of Constant thanks to Wilson and one of his machines and - unknown to the survivors, one of Engie's teleporters. Unfortunately, the survivors weren't the only ones released from Constant. Realities bleed and mix together. The Administrator, Grey Mann and Charlie are in a three-way power struggle with one another and the Survivors, Mercs and Miss Pauling are caught in the middle of everything, like always.
