I have very fun and unique play style right now. It involves a nova pistol and my left hook. Really.

My modules
Armor:Air Stomp (that no fall damage upgrade is worth the practice).
Stealth:Covert Ops (you need to be silent when your going for a quick melee kill.)
Power: Mobility Enhanced (You got to have it if you move fast 24/7 which with this set up is a MUST).

Oh and my back up, lol, is my trusty K-volt with nothing on it.

I can run around like mad get tons of kills and if I actually start planing my moves then the chaos beings. This is great practice for you pistol skills and a random Air stomp or two(you NEED that first upgrade so you can jump off buildings.) Also sliding is kind off a must since you cannot win a firefights. The whole point of this set up is to be in one. You fire a few rounds into someone, melee and GET OUT OF TOWN. You win by flanking fast and picking people off one bye one quickly and quietly.

What is you pure fun set up?
