Thanks Jimmy! I don't know if we'll ever do a big box expansion, as I'd like to keep expansions affordable, but the cooperative idea is intriguing. I think it's actually possible to play that way already using the Automa cards, though there isn't an official variant for that yet.
I posted a variant that allows both competitive and coop play with any number of humans and Automas.
It hasn't undergone proper playtesting, though, so as Jamey says we don't have an official variant for it at this point.
The thread with the variant is [thread=1469589]here[/here].
We've also had some very vague ideas about making a rather different coop version where the players play against a very different and powerful enemy centered on The Factory. That's likely never going to happen, though.
