Iron Brigade – formerly Trenched – is coming to PC next week.

The Double Fine third-person shooter/tower defence hybrid will be available on Steam on August 13.

The game's only expansion, Rise of the Martian Bear, will be included.

"We hope you dig Iron Brigade on PC. We had a blast making the game. I can’t wait to see some new players get their hands on it!" said project lead Brad Muir.

A price is yet to be announced.

The Xbox Live Arcade release of Iron Brigade has been reduced to 800 Microsoft Points.
