OK, I realize this game is VERY new, but here's a few interesting combos I like so far.
Melee 2+/Katana/Cyberarm - You CAN have two cyberarms, right? That makes this even better!
Flock of Geese/Booby Trap/Booby Trap - Two runners nuked quick and easy!
Knuckles/Heavy Armor Full Suit/Harley Scorpion - Gah! That's a LOT of Armor to pierce!
