I played as a female human soldier, armed with a Thokin assault rifle and a Carnifex pistol. With the left shoulder button I could toss grenades, while the right let loose a “concussive shot” that stunned enemies, then lifted them off the ground and spun them in mid-air. It felt a bit like a fast-acting biotic power, but with a very small area of effect and just a touch of homing. By pressing both shoulder buttons at the same time, I was able to supercharge my assault rifle for a short time.
