This is where Survivors Unmatched was connected to those crossovers. Think of the original ETO but in the apocalyptic AU.

It is more than the broken than the original ETO timeline.

The person behind the team is Gaster, Annette, Sadny Bin and so much more to appear, they gonna interfere a lot more than enough than the mastermind and the good guys.

Before you'll get to the main battle stage menu of the connection of those crossovers, the player will have to traverse this pitiful world out of the existence, and this is where the encounters might occur into falling place to place.
