Players search for three different things under "Subnautica 2 codes": limited reward codes, item-code or console-command lists, and door keycodes. This page separates those search intents so you do not waste time on fake code tables.

Trust note: Last checked July 7, 2026. The Bilibili cosmetic code is listed with an expiry date of July 1, 2026 (expired); giveaway keys may run out earlier than their event dates.
