It's been almost three years since Double Fine Productions released the alternate-history tower defense/shooter hybrid Iron Brigade on Steam. That's a long time to wait to release the game's first update, and yet here it is: Some bug fixes, some tweaks, and, most important of all, the end of Games for Windows Live.

There's actually a pretty good reason for the new update, in spite of the years-ago release date. Double Fine announced yesterday that it has acquired the rights to the property from original publisher Microsoft, and thus it will now be a self-published game. "The great thing about this change is that now there are no obstacles to us creating the best possible experience for players," Iron Brigade creator Brad Muir said. "We have fixed all known issues as well as provided a great matchmaking experience for multiplayer. Vlad and his Monovision Menace are on the move again! In the best possible way!"

Iron Brigade was originally released in 2011 for the Xbox 360 under the title Trenched, although the name was quickly changed to Iron Brigade after a pre-existing trademark for a tabletop wargame named Trench came to light. The PC version, which includes the Rise of the Martian Bear DLC, came out a year later.

If you're curious, now might be the time to give Iron Brigade a shot. To celebrate the update, Double Fine has put the game on sale for 80 percent off its regular price, dropping it to $3/ 2 on Steam until June 2.
