Finally. Radiant Silvergun for the Sega Saturn was my jam, and now Treasure's beautiful shmup will be my new jam on the Xbox 360. Yes, the XBLA version of this fine game is coming our way on September 14. Treasure's webpage says so.
You can play in both Arcade and Saturn modes in this version, with your scores now going to online leaderboards. Please do not look at mine! Also, there's online co-op play, downloadable player data and improved visuals. HNNNNGGGG.
