A major patch and downloadable content for Tom Clancys EndWar is due out on Xbox Live today, with PS3 gamers getting it tomorrow.

The patch will expand the games multiplayer to a maximum of eight online players; this will allow 4v4 play in the skirmish and Theatre of War modes. Meanwhile, new content appears in the form of four new maps, three unit upgrades and 10 achievements/trophies for 800 Microsoft points ($10). The new maps will only be playable in skirmish mode.

Unfortunately for PS3 gamers, the multiplayer patch wont be releasing until next year, though the content should be available starting tomorrow.
