This map has some pretty fun moments, such as the big fight in the outdoor area (prime rocket fodder), but I think other parts are drawn out too much, such as the leadup to the red key. I had rockets left over, so I could have found more places to use them or at least skipped some of the ammo pickups. I think a great run could get under the par time (6:30), but getting under 7 minutes is good enough for me.
