Any tactics?

I've been trying to beat Mile High Club on veteran for over three weeks. I have tried almost every conceivable angle of approaching the enemies, and I still die. Any suggestions/hints/tips?

 

I've done it loads of times.
Once you get the hang of it, its easy. You just need to find a route that suites your style of play and keep doing it until you get to the end.
If you find yourself dying a lot, then try to take a different route, and if you don't reach the end in time, don't kill everybody, or don't stop in one place for too long.
If my xbox didn't have RROD I'd do it for you myself if you have live :S
