Mass Effect 2 - Tali: Treason, Insanity Mode on Adept
Companions used Tali (obviously) and Jack. Swapping between SMG (Locust) and Assault Rifle (Geth Pulse Rifle). Using a mix & match of skills, Pull, Singularity, Warp and Energy Drain. Combat Drone to distract (Attack Combat Drone but I have used the AOE one in the past, both worked for me). Using Jack's Warp Ammo (Squad Ammo version) as the Advanced Training skill is taken by Energy Drain.\n\nThere are other companions I could have used instead of Jack (Miranda would have been better due to the party buff and Overload), but I like biotic synergy with her Pull. I did countless runs with Miranda and I liked a change. This set up however allows me to:\n\n1. Have personal shields on demand with Energy Drain\n2. Forsake Overload as Energy Drain does the shield stripping (so Energy Drain does 2 functions in 1)\n3. Have Warp Ammo, although it's just level 3 (since it's Jack's Squad Ammo)
