MULTI SLICE EXPOIT
Take a weapon and start slicing in normal fashion. Cut the first wire. Do not cut the second yet. At this point you have cut the negative or positive wire with one left. Now right on the weapon your slicing in your inventory and bring up the radial (you should also add a damage power up to your weapon for an increase in the slice). Now you have your slice menu up and the radial up for the weapon.
Please note, I can't remember which one but you need to click on the next wire your cutting on the first slice menu. Don't worry because you won't screw it up, but you just won't advance till you click on the first slice menu.
Now what you need to do is click slice on the new radial from your inventory and then hit enter (which advances your first slice menu) at the same time. Its really no brainier and you get two slices at once.
Enjoy and try not to get banned!
