Good bloody luck when/if you get to One Shot One Kill and Heat. Those levels kicked my ass from here to a full 360 degrees around the circumference of the Earth.Don said:CoD4 on Veteran; still not completed it.
Edit: In fact, have only done 2 proper levels; I couldn't get past Charlie Don't Surf's TV station.
Anyway, Mass Effect 2 on Insanity was no cake-walk, mostly because staying out of cover for three femtoseconds got your shields shot off if there were more than two enemies. Though playing as a Sentinel would make it more managable.
