Herotigo2: Dev has said in steam forums that they will if enough demand for it.. Obviously everyone is demanding it and they have yet to do it mainly cause they just don't care they got their money and now they taking off
And this is strange because how will they ever estimate demand?
How do they communicate with people like me who didn't buy the game simply because I can't play it at home with my kids. It's not like I'm bugging them weekly with this question. I just put this game on my "looks good but don't buy" list and occasionally come back to see if it's had an update.
Who knows how much money they would have had if they just included popular features which they have no reason to exclude in the first place? Come on! This is a co-op type game.
