Rocket jumping
It is a good choice to use ultima cannon to rocketjump around the map. It is possible to obtain the uberhealth by rocketjumping. For those players who are lousy players,they can rocketjump onto one of the bunkers and try to shoot at enemies. Hopefully they will not notice you and you can continue shooting.
The judge is a average handgun that does 34 dmg and 51 dmg head/nutshot. Not worth buying as it is unaccurate and weak.
