Ensemble’s upcoming console RTS Halo Wars is already breaking records. Today, Major Nelson revealed that the game’s XBL demo (available here) has been downloaded by an astounding 2 milion Xbox Live gold members. Not only does that beat XBL’s five day record, but it also set a one day record for most demo downloads during that timeframe. All things told, the feedback for the demo seems very positive, and Microsoft and Ensemble can likely count on a good number of those downloads to translate into full retail sales.

Too bad Ensemble got shut down. Microsoft might seriously regret that decision when the game hits shelves on March 3.
