My favorites are the Dual Raptors with the acid mod, the Vulcan Cannon with the shock mod, and the Silencer with the mini-bomb mod. All of mine are at level 99, and Bomba is right. With that much speed and less ammo, you run out of ammo quick. My least favorite actual weapon is the Quasar Turret because the will still fire if something is already dead. If I'm gonna use them, I usually give them the freeze mod because if you give them the acid, they won't stop firing even though the enemy would die from the acid. I do like using the holo-shield launcher alot, but just to mess around. I needed to train it up, so i found a turret in one of the levels and surrounded it with 4 shields and kept running in circles around it to train them up. It was really funny.
