I never quite adjusted to the framrate but some stages where worse than others (I hated the swamp but the research station was pretty good on both out and in-door sections for example). The music was nice but the voices where retarded at times, enemies sounded like they where close but were infact standing 50 meters away.Team mates yelling "falling.. back" six times in a row or just saying things that doesn't make sense, good voice actors though.
Do a lot of fps games have a run button btw? I thought it was a nice feature and I didn't mind the fact that you couldn't jump, infact I hope they skipp it next time around.
