I have to agree the Gauss and Scatter MAX are quite good, the Gauss is very accurate in distance but really sucks up close. The Scatter is really quite scary up close and indoors.
About the VS, the Quasar and Pulsar are awesome, the Pulsar DOES have a tight COF but the dropoff damage hurts, and the dual ammo feature is great since I can shoot grunts and MAXs at the same time with instant switching. A couple of my VS outfit members complained about the Pulsar until I told them how to properly use it and they change their mind to "hey it's not a bad gun after all".
