Several Double EXP Weekend playlists are useful for gaining this achievement, including Mythic Brawl and Ranked Living Dead.From there, one can melee any players that rush for the ball. During an Oddball match on Guardian, one can go downstairs, grab the ball, and run halfway up one of the small ramps overlooking the central 'arena.' At that point, one should drop the skull and hide behind the door.One can activate the Bubble Shield to draw enemies close, and then use the Shotgun to mow them down when they enter. A tricky tactic is to find a Shotgun and a Bubble Shield.

During a King of the Hill match, sniping players at the hill is a valid tactic.

Alternatively, one can lie in wait near the hill with a Shotgun, Gravity Hammer, or Mauler. Players at the hill will often be too preoccupied to avoid the turret until it is too late.

The turrets on The Pit can be useful when playing on that map in a Crazy King match.

One can also rush for the Energy Sword during a King of the Hill match. Players that are skilled with the sword may be able to gain Triple Kill, Overkill, Steppin' Razor, and possibly even Killing Frenzy all in the same match.

One way to get this achievement is to use an Energy Sword on The Pit during a Swords match.
