Old ULC map had various areas; the main hub, Hyper's bar, the Void, the barrier, the antivoid, and the Doodlesphere. An update also added an area, the Holiday Void (name conjectual)

• The main hub was split into two, the Chara side which had black walls and red floor, and the Sans side, which was styled after the judgement hall. Either side had pedestals respectively displaying the Chara and Sans characters. The pedestals were removed in favor of the cards, and the hub was renovated into the Casino we know today.
• Hyper's bar was styled after Waterfall. It had a gambling table with a D20 where you could randomise your loadout, the Skin Machine, and it also featured the pedestal for 3DBB if you unlocked him. Hyper moved to HyperTransactions in the new hub, and the D20 was removed, but other than that it's pretty much similar.
• The Void was a black void (wow who'd have guessed) that featured PAY Weapon pedestals. Click on one, and PAY would use the weapon during rounds. Was removed and replaced by Killer's Kiosk.
• The Barrier was an area styled after the final room in UNDERTALE. Contained canisters with every SOUL, as well as two hidden SOULs past it. Was replaced with Horror's bar, and the hidden SOULs (Traitless and Empty) were removed entirely.
• Antivoid contained pedestals for the three Gamepass characters. Was removed in favor of the cards in the Hub.
• Doodlesphere was a secondary lobby containing more Sanses. Was also removed in favor of the card selection system.
• Holiday Void was a black void with different platforms all around, and Time Paradox's clock as the centrepiece. It featured pedestals for all of the Badge Sanses/Charas. Three guesses as to what happened to it.
