Deep Frost is single-player social-deduction horror set in a failing Antarctic research station. A parasitic intelligence called the Thaw is copying the crew. Keep the outpost alive, build your case and decide how much trust you can afford. Twelve researchers. Up to nine days. Something is wearing their faces. INVESTIGATE THE STORYQuestion researchers, inspect station records and compare accounts. Keep track of your sources in the Case File and your own field notebook. A contradiction gives you a lead; it does not prove someone is infected. TAKE A SIDE AT THE ROUND TABLEAccuse someone, defend a person you still suspect, or keep your theory to yourself. Your public statement and your ballot are separate decisions. Researchers can react to what they witnessed or learned about you. KEEP THE STATION ALIVEFailing systems threaten everyone. Investigate equipment problems and choose how to respond while the crew's suspicions grow. A successful repair can help the station without clearing anyone's name. RETURN WITH DIFFERENT LOYALTIESEach expedition draws twelve researchers from a cast of 48, with new hidden roles, events and relationships. In the full game, later expeditions deal you a hidden role: usually Crew, sometimes Thaw, secretly working to divert suspicion. Your first expedition, Daily stations and the demo always start you as Crew. Close reading, uncertainty and social choices drive the tension. TRY THE FREE DEMOPlay the first three days, ending after Night 3. Day 1 teaches voting with a practice ballot. The full campaign continues into blood testing, later station threats and extraction. Reading and play time vary.
