found a cool strategy for those who enjoy running into masses of people and taking out as many as possible.
First off, you'd need the surge implant, and at least med assault. Then choose your mass of enemys, and run in when they least expect it with surge on moving around * a single target out of the mass* with your gun firing. If you do this properly then you will be able to be as close as possible to them ciricling around them firing , and they will be so confused and disoriented that they will not be able to do sufficient damage to you, and then move to your nearest enemy and do the same, all the while your occasional misses go into the mass of enemys. This is not only effective for taking down multiple targets, but also really fun
( i discovered this after falling out of a mosquito with only my cycler and a lot of ammo and surge into a disgusting mass of new conglomerate. Lets just say blood doesnt wash out easy
