Hitting up the Xbox Live Marketplace today, it seems that the Frontlines demo we were promised way back has finally arrived. Major Nelson hasn’t updated us so we don’t know any of the regions it is available in.

Update: Major Nelson has now updated his blog, so we have the details after the jump.

Early reports from those that have already played it are very disappointing. Apparently the framerate is rather poor and you’ll want to delete it after five minutes of play. The controls are also clumsy, which isn’t very re-assuring after we’ve been spoiled with the likes of Call of Duty 4 and its brilliance.

But don’t let us put you off, share your thoughts in the comments.
