How the hour was fixed

On 12 September 2026 the studio named 5 November 2026 for Windows. On 3 November 2026 the countdown post said 18:00 CET and 12:00 PM EST. SteamDB lists 5 November 2026 at 17:00:00 UTC. I treat those as one unlock, not two. The same announcement covers Steam and GOG. It does not give GOG a separate second.

Reviewers and video makers were offered the full game from 2 November 2026. That is why reviews dated 2 to 4 November exist before the public unlock. Preload is blank here: no store page I read states a preload.

Switch

The 12 September announcement puts a Nintendo Switch version in the first quarter of 2027. It does not say Switch 2, and it does not name a day. That line has one source, the developer. I am not filling the gap with a guess.

Questions

What time does Underkeep unlock?

17:00 UTC on 5 November 2026, which is 18:00 in Prague and noon in New York (EST).

Is the Switch version the same day?

No. The studio plans a Switch release in the first quarter of 2027 and has not named a date.

Can I preload it?

No public page states a preload. The cell stays empty until a store says otherwise.
