This week's Xbox Live Arcade releases are officially confirmed as Marathon: Durandal and Spyglass Board Games. The former is, of course, a remake of the classic Bungie first person shooter sequel, one that hearkens back to a time when guns were screen-centered and the Macintosh actually had timed-exclusives. The latter contains Xbox Live-enabled chess, checkers, reversi and mancala plus sports Xbox Live Vision camera support, perfect for showing off your junk.

Marathon: Durandal is 800 Microsoft Points with Spyglass Board Games a mere 400.
