Step 1: Play as a Titan. Step 2: equip yourself with one of those high-fire rate, low impact auto rifles. Step 3: Run around the map like a maniac spraying bullets wildly and punching the Hunters and Warlocks that make up every other player on the server to death.
Don't worry about getting kills with the rifle, it's only there as a hail of spitballs to keep your target from shooting you in the head as you close in.
Also, there are few things more satisfying than charging a control point that has 4 players from the other team camped out for the capture and doing the Titan's apocalyptic bellyflop special attack. You wipe them all out in one go and then just chill there and take the control point for yourself.
