Deep Frost is a single-player social-deduction horror game set in a failing Antarctic research station. A parasitic intelligence called the Thaw is copying the crew, and the crew votes on who to purge.

The free demo is part of Steam Next Fest, from October 19 to October 26. It covers Days 1 to 3 and ends after Night 3. In the demo you play as Crew. Question the crew, check station records and compare accounts in the Case File. A contradiction gives you a lead; it does not prove anyone is infected. Day 1 teaches voting with a practice ballot that removes nobody. From Day 2, every vote purges someone, and the colour of the ash shows whether they were Crew or Thaw.

New in the demo's latest update: the purge page shows your own vote under the ash result and, if you confirmed one, a clash between that person's own account and a station record. Each night holds for a moment in the dark before anything is revealed. Each ballot lands with a low thud as the votes are counted. Each crewmate opens with their own signature line when you first talk to them. After Night 3, an optional PROCEED TO THE REVEAL button shows who was Crew and who was Thaw.

The full game launches October 27, 2026. It runs nine days and continues into the blood test, later station threats and extraction.
