In an interview with Kotaku, the lead designer, Dustin Browder, mentioned that the game was? “99 per cent done, but that last one per cent is a bitch”.
Browder also added that the missions were all considered to be playable and that the units were in place.
“There’s something in for everything?it’s whether we like it or not that’s an open question. It’s the tuning and polish that really takes us a long time, and that’s where we get into the unknowns.
“Like we could do a play-through next week that we’re like, ‘Wow this is really great.’ Or we could do a play-through and we still have 250 items we wanna fix. You know, historically speaking we’re doing pretty well. We’re getting there. But I don’t know for sure yet when we’ll be done.”
