Looks like last month's speculation was true after all. Microsoft has just sent out word that come this Wednesday, they will be updating Xbox Live Arcade with Bungie Software's old FPS classic, Marathon: Durandal.

This game originally made its way to the Macintosh platform, and is something of a direct ancestor to the Halo franchise; Norse names, player-controlled super-soldiers, and all. Marathon's XBLA release will include redrawn graphics, revamped controls (for the 360 controller), and networks support for multiplayer mode.

Another game also to be expected this Wednesday is Spyglass Board Games. This title is actually a collection of classic board games like chess, checkers, mancala, and reversi. Spyglass Board Games for the XBLA will carry support for the Xbox Live Vision camera, as well as integrated video chat.

Freeverse Software is reportedly preparing both Marathon (800 MS Points) and Spyglass (400 MS Points).
