Mark "Have Blue" Levin of Freeverse has written up a Gamasutra postmortem of their port of Marathon 2: Durandal to the Xbox 360.

What's revealed is that the Xbox version isn't so much a port as it was almost a complete from-the-ground-up rewrite:

Retronauts continues its contributions to 1Up's ongoing Halo 3 coverage by taking a look back at Marathon 2. In case you've been under a rock since July, Freeverse has ported the game to XBLA as Marathon:Durandal.

Thanks to chewpathingy in the HBO forum.

1Up's Halo 3 coverage continues; this time, the Retronauts Blog is traveling further back in time to the colony ship Marathon. There's also an indication from Bruce "Hippieman" Morrison from Freeverse in the comments to that entry to the effect that if there's enough interest, that Marathon Infinity and even the original Marathon can also be brought to Xbox Live, just like Marathon: Durandal has been.

HBO is announcing the winners of their latest Seven on Seven contest. This last competition was to put the Master Chief into an older Bungie game. The seven winners get free downloads of Freeverse's Marathon:Durandal from Xbox Live Arcade.

Ma1agate tipped us off that IGN has started offering a walkthrough for Marathon: Durandal.

Freeverse's XBLA port of Bungie's FPS classic Marathon 2: Durandal recently got an auto-update; you may have noticed the last time you played the game. Freeverse's web page has a news post up about the update. The highlights are:

• Survival mode in demo
• More sensitivity controls
• FOV setting (for people with motion sickness problems)
