The Outer Worlds 2’s first DLC arrives December 2
Obsidian Entertainment has officially announced the first narrative expansion for The Outer Worlds 2. Titled 'Side Effects Guaranteed', this is the first of two planned story installments, with the second part expected to arrive in spring 2027.
The expansion, set to launch on December 2, introduces a new storyline triggered by a distress signal from a derelict ship. Players and their crew will find themselves caught in the middle of an abandoned settlement, a power struggle involving the Sub Rosa criminal organization, and the mysterious fate of a team suffering from a lethal condition characterized by explosive cell death.

New Arsenal and Gameplay Mechanics
Beyond the narrative, 'Side Effects Guaranteed' will introduce five new weapons to the player's arsenal. Among them is the Immobilizer, a device that negates gravity around a target, allowing them to float in mid-air—a mechanic designed to synergize with grenades or the Tactical Time Dilation device. Other additions include the 1/6 Resolver, which delivers a critical hit on every sixth shot, a weapon specialized for creature damage, a Tossball Stick, and a new plasma-based energy weapon.

The DLC also expands the core RPG systems and exploration options. Key updates include:

Accessibility and Character Customization
To facilitate immediate play, Obsidian is adding a feature to the main menu that allows players to jump directly into the DLC. This option loads a pre-made level 27 character with customizable skill points and perks. Additionally, a new update arriving alongside the DLC will allow players to respec their characters at any time. For those seeking more control over character progression, a new custom game option will allow players to adjust the number of skill points earned per level.

The events within this expansion are designed to occur just before the 'point of no return' in the main game. The consequences of player decisions in Elysium Valley are expected to lead directly into the second part of the story expansion in 2027. 'Side Effects Guaranteed' will be available on December 2 for the base game, the Premium Edition, or as an upgrade for the Premium Edition of The Outer Worlds 2.
