Unstoppable: Outerdark is an expansion for Unstoppable released in 2027 for 1–2 players, 45–75 minutes per game, and ages 14 and up. It was designed by John D. Clair and its main mechanics are Hand Management, Cooperative Game, and Solo / Solitaire Game.
Beyond the limits of controlled space lies the Outerdark: haven of criminals, vagrants, and those who don’t want to be found. Here, the once-silent corridors of Kotahi Station now echo with the grinding of gears. Metal hands solder pieces of scrap into flesh. Cables and tubes filled with saline solution pump into the back of a thick, scaled neck. The room is lit by a glowing yellow blade. With a hiss, the tubes disconnect to free the cyborg. A drone hovers over rows and rows of similar cyborgs, horrifying amalgamations of synthetic and organic. A roar rumbles through the Outerdark, an omen of what’s to come… The Unstoppable: Outerdark expansion adds three new bosses to overcome as well as two new heroes you can use. Special double-slot upgrades add more options, while new keywords for both heroes and threats shake up the battlefield. -description from publisher

Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Unstoppable: Outerdark is 45–75 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
The catalogue lists Unstoppable: Outerdark for ages 14 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
