The first part of a two-part story expansion for The Outer Worlds 2, titled Side Effects Guaranteed, is scheduled to release on December 2. The narrative follows a distress signal from a derelict ship that leads the player's crew into a power struggle involving the Sub Rosa criminal organization and an abandoned settlement.
The expansion introduces the new region of Elysium Valley, which includes unique quests and new facilities. Players will also gain access to five new weapons, such as the Immobilizer and the 1/6 Resolver, alongside a level cap increase to 36, new perks, and a new Sub Rosa radio station with 20 songs.
A simultaneous update will allow players to respec their characters at any time and adjust skill point gains per level in custom game options. The DLC can be played directly from the main menu using a pre-made level 27 character, or it can be accessed through the main game just before the point of no return.
Announced release date: 2 Dec 2026
