Unlike the first game, using powers is not solely unlocked by you. You will want to go into the game options and set your teammates powers to manual. The following teammates have biotic powers for which will gain you the achievement.
Miranda, Jacob, Thane, Jack, Samara/Morinth, and YOU (Maybe)
With the above teammates in your party use a combination of the following:
* Pull - Throw
* Pull - Slam
* Pull - Charge
* Pull - Warp
* Singularity - Warp
* Singularity - Shockwave
If you add a teammates bonus power after completely their loyalty mission, such as Miranda's Slam, then you can also perform this with only one biotic in your party. For some reason if I hit both powers together at the same time, it was hit or miss. If you use a power, then wait a second, and use the other... it seemed to work every time.
If you leave negative feedback, please let me know, so I can correct. Thanks!
