Double Fine has announced that Iron Brigade (which is the updated version of its great game Trenched, renamed and revamped for sale overseas) is now available worldwide on Xbox Live Arcade. The game is available for 1200 Microsoft Points (about $15) and Double Fine is also selling an official release day I-shirt (not a T-shirt, they say -- "that would get us sued") for $20 on its website.

Anyone who already owns Trenched will find an update when they log into the game, and that update will not only change the name, but it will add a whole list of new features, including new items, leaderboards to compete on, and a new survival mode. We loved Trenched back when it released in June, and we're sure that by spending a little sit-down time with Iron Brigade, we can probably learn to love it, too.
