AVA Train Extreme: Any tips and tricks?

[aznfreak93]

As title says, have you guys been able to find tips and tricks on beating Train Extreme? I have been able to get through Rounds 1 & 2 easily (sometimes round 3), but have difficulty later on.

Assume that I have the Train Boost (2nd Special Wep slot, 20%+ HP regen, and 3 level points).

And don't just suggest respawns.

ROUND 3 BOSS - ROBOTS GET RID OF THE ROCKETS/BOMB/MACHINEGUN ONES FIRST
THEN THE INVISIBLE.SAVE THE RED ONE FOR LAST( WATCHOUT FOR PIKES)
ROUND 4 BOSS - 4 CHAINSAW GUYS GET RID OF THE EXTRA MOBS FIRST WHEN THEY SPAWN
THEN HEAD TO THE BRIDGE (CENTER OF MAP) JUMP ON THAT ELEVATOR THINGY, YOU WILL SEE EACH SIDE HAS ONE OF THOSE THINGS YOU CAN GET ON TOP OF.
STAY THERE AND X9 AIM FOR HEADS
ROUND 5 BOSS - ROBOT GORILLA KILL ALL HIS HELPERS FIRST
ALWAYS AIM FOR HEAD
WHEN THE CLONES SPAWNS KILL EM FIRST. THEY SPAWN WHEN BOSS IS 30 PERCENT HP.
