Bangai-O HD: Missile Fury won’t be out until next year, but Treasure is using the time to add a new feature.
That new feature is cooperative and competitive multiplayer, which puts it roughly in line with the Nintendo DS’ Bangai-O Spirits. No word on whether the multiplayer will be local only or online compatible.
With the delay though, don’t expect it to appear on the Xbox 360 until next spring.
