Crimson Dragon may not quite live up to its predecessor's legacy, but it is the sole Xbox One game that will let you fly a dragon. And if there's anything better than flying a dragon, it's flying a dragon wtih friends. Grounding's shooter will let you do just that, thanks to a free update that adds co-op and competitive multiplayer.
According to Play XBLA, the update is available upon starting the game. At 4GB, it's pretty big, especially considering that the base game only comes in at 6.88GB.
Beyond introducing co-op to the on-rails shooter, the update will also feature a new "Insane" difficulty level, for anyone looking for an additional challenge.
