Anyone remember Iron Brigade (aka Trenched)

I remember this game being on Xbox Live arcade and it was a gemmy tower defense game and (you) and 3 other friends play as soldiers in mechs. Sometimes I still pick it up now and again to play with buddies but I have never ever seen anyone talk about this game for a very... very long time. Really sad that it became forgotten but I suppose that's a better fate than it being discovered by trannies like postal was. Not an amazing game but it was really fun
