Sure, I had the machine gun, shotgun, and pistol and I was using rolls and slide and bullet time. Im not sure if infinite sliding was intended but I made use of it to get around quickly. It seemed that no matter what I did my health would just get whittled away, dashing in to try and pick up health drops usually ended in a net negative, running away to safety and cover wasn't effective since there was no regen it just seemed to delay the inevitable.
