The first half of the mission wasn't as bad, but the 2nd half was so annoying and i remember i died like 15 times or more. Because there's 'so' many enemies there and one of them endlessly respawns in the little square building on the right side behind a wall (inside) as you go in, and he doesn't stop coming out the door until you make in and kill him at the spawn point. That was the part that i was getting so annoyed with coz if i died before i ran inside quick enough, it takes you back to the start of that 2nd area and you have to kill all those enemies again. It was such a pain.
