Sure, here
http://www.youtube.com/watch?v=JTqT7Ag7DYkany class also can, but I suggest you start out with Turian Sentinel and Human Engineer like that guy in the vid.
The most important power you should upgrade first is overload, after you've upgrade the first 3 ranks, go with chain overload(4th), Neural shock(5th). and chain overload again(for 6th)
then for fitness upgrade shield and shield recharge(ignore all melee upgrades)
for Alliance training upgrade, after the first 3 levels, take increases weight capacity, power damage, 6th upgrade(weapon damage) could be ignored if you want.
for Incinerate, take damage, damage over time, and damage to armor after the first three levels.
Also if possible, make sure your cooldown is 180%-200%
I suggest using the geth SMG.
So in your opinion which one? Cuz now i use only quarian infil for silver and human vanguard for bronze . Only got quarian infil and drell adpet x.x
