XBLA Radiant Silvergun includes both arcade and Saturn modes

Before the famous (and, soon after, very expensive) Sega Saturn version of Treasure's Radiant Silvergun arrived, the shmup was an arcade game. The Saturn disc included both the arcade original and a "Saturn mode" with new voice acting, extra levels, and additional bosses.

The upcoming XBLA version will maintain the choice between "arcade mode" and "Saturn mode," both with optional updated graphics, Andriasang reports. The XBLA version also offers two-player online co-op, leaderboards, and an "Ikaruga" mode, which Treasure still hasn't detailed.

Radiant Silvergun will cost 1,200 Microsoft Points ($15, or so much less than the Saturn game's cost) when it comes out sometime this year.
