No. Limbo: Eternal War was designed as a skirmish product, and it would be quite difficult to translate this experience into a solo / cooperative mode. There have been lots of requests for this during the campaign, but if we were to make a solo / cooperative mode, it would likely be in a future campaign, as it's not really feasible for us to make a satisfying experience AND deliver the campaign on time.
There will be a 1 v 2 and 2 v 2 option later in the campaign. Stay tuned for news on that!
