Mass Effect 2's final boss was pretty damn easy. Great game as it was, the final boss was a joke. I'm pretty sure that if you just stayed in cover the boss had absolutely no way of killing you. At all. As long as you weren't a complete idiot, the boss literally couldn't kill you. What kind of boss is that!?!
Maybe it was because I was playing on normal, but the ONLY thing I had to do was stay in cover. Even when the collectors came during the boss fight, the boss's big attack would kill them too, so all I had to do was sit behind cover, shoot at a big glowing red spot, then duck back into cover. I like ME2 a whole lot, but that was a big, BIG disappointment.
Plus - giant terminator? Really? Really? That's what they used as their inspiration? I was half expecting it to say "I'll be back" in an austrian accent.
