The Matriarch boss fight is probably one of the worst boss fights in Gears history. I was really digging the game but the amount of times ive died because I was caught on an invisible wall around the ice is staggering. Not to mention it takes eons to get behind her when she is forzen, and what weapons do they leave you? The retro which kicks like a mule and a sniper rifle... In a close quarters fight. Trying to do this solo is painful. Oh let's not forget to blind the player in red connection mist. Are the later bosses harder than this?
I actually quite enjoyed it. For me, it was the hardest moment in the game and everything else was relatively easy. I think I spent about an hour on that battle. Was expecting the bosses of Act 3 and Act 4 to be of similar difficulty but they weren't. Was disappointing.
