The Outer Worlds 2 expansion Side Effects Guaranteed arrives December 2nd

A Distress Signal and a Deadly Cure Hunt

A distress signal draws you and the Incognito crew to a derelict ship. Its occupants are in suspended animation because they have been infected with something causing explosive cell death, so the search for a cure takes the crew to Elysium Valley on Eden.

Two Sub Rosa agents approach the situation with conflicting aims: saving or sacrificing the infected crew. Their plans involve a Protectorate settlement and the future of Sub Rosa, and your decisions determine the fate of the settlement, the crew, and Sub Rosa itself. As the announcement puts it, “Side effects may vary.”

Progression, Companions, and an Alternate Start

Beyond the story, the expansion raises the level cap from 30 to 36 and adds more than 15 perks. Players can also select from four new Flaws, receive new weapons, armors, and outfits for every companion, and listen to a new Sub Rosa-run radio station featuring 20 new songs.

An Alternate Start option lets players move directly from the main menu into the DLC with a custom save. The expansion is listed for XBOX, Battle.net, PlayStation 5, and Steam, with standalone pricing of $14.99 and access also included in the Premium Edition or Premium Edition Upgrade for The Outer Worlds 2.
