The official OXM from across the pond (UK version) had an article
that Double Dragon
, another classic 80's side scroller is confirmed as coming to Xbox Live Arcade in the near future. While no official announcement has been made by Microsoft, this would make sense as DD was hugely popular back in the day.
The article claims the game will only be 12.56MB, but feature enhanced graphics and co-op play through Xbox Live. There is no cost (likely 400 points) or release date yet associated, but Xbox 360 owners can still rejoice in the seemingly unlimited line of classic arcade titles promised to XBLA.
