Well it finally happened; Double Fine decided that Trenched needed a name change - and not just in Europe anymore. During a recent Giant Bomb’s Big Live Live Show Live! Double Fine's Brad Muir and Greg Rice announced that Trenched would now be called Iron Brigade. The main reason for the worldwide name change is so that the company can completely avoid any possible confusion with the board game Trench. Its owner had said that there might be some brand confusion if Double Fine continued to use the name in Europe because he was planning on developing a game from the board game property.
If you have already purchased Trenched you will receive an update that changes the game's title to its new game. Luckily the update also includes a new survival mode, new weapons, new costumes, and some other bits and baubles. This is a title update, which means you'll need it to continue playing.
