Citing bugs in network modes, problems with the game’s matchmaking due to the number of platforms being supported & the fact that the engine used is no longer being updated, the team has actually had to manually reprogram parts of the engine themselves.
Because this is the 3rd delay they are waiting to announce a new release date until they are certain it will be ready, but are realistically expecting a Spring 2016 date.
With the amount of games that come out broken I’d rather see a game dev delay to finish the game than release & patch the game later. It’s not like we don’t have other great games to play while we wait.
