Mass Effect 2 - Recruit the Convict (Soldier on Insanity)

Using the Vindicator Battle Rifle and Mantis sniper. I swap between Disruptor and Incendiary ammo although I mainly use Disruptor due to shields. Garrus has AOE overload, which I use to also overheat enemies' weapons (so sometimes you'll see me hit someone with it who doesn't have shields.) Kasumi has Heavy Shadow Strike. I use Energy Drain as special power, but I don't even use it that much. Soldier doesn't really feel like a class that needs extra powers.
