About Unstoppable: Outerdark, from BoardGameGeek:
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.
