What weapons do you like to duel wield? Or do you like to have a hand free for granades? I like having Plasma Pistol + SMG, the fully charged Plasma Pistol will totally drain the shield while the bullet hose is soaking your enemy and taking away thier health. Also I like having the Magnum + SMG. Again, the SMG is pouring bullets into your wnemy while the Magnum delivers some lethal headshots.
