Start with 10 Dex, 10 Per. Put at least your first 4 stat points into Dex. Make sure you get Spec Ops and Commando, and Quick Tinkering. If you can find the points for it, you'll also want 7 Str for Full Auto. That'll give you max burst with your SMGs. You're going to want to be stealthy, but you can sneak *just fine* with 3 Agi. If you don't want to go 6 Agi for Sprint, though, you might want to consider picking up Psi Empathy and Temporal Manipulation. You'll be very squishy, but your bursts from stealth will be devastating. You'll see other feats that you need, like Critical Power, Blindsiding, Ambush, and a couple others. Probably also should pick up Grenadier.
