Overkill (achievement)

Overkill is a Halo 3 multiplayer achievement. It is awarded when the player gets an Overkill in a ranked free for all playlist. This Achievement gives 5 Gamerpoints to the player. Overkill also unlocks the head piece for the Elite Commando Armor and shoulders for the Elite Ascetic armor.

It is represented by a bronze medal with four green stars.

Difficulty
This Achievement has been antagonized for its difficulty to earn. Currently, there is only one playlist that falls within the conditions. Since the playlist, Lone Wolves, originally only supported 5 player per match, for Overkill to be unlocked a player had to kill every other player in the game within four seconds of each kill. This was proven very difficult, and many players opt to get this achievement simply in an achievement match. This was rectified and made slightly easier in a recent update, where the amount of people allowed per game was upped to 6.

It was briefly possible to earn this achievement relatively easily during the Halloween zombie special. If you started as the alpha zombie on a "creeping death" match, it was possible to have four or more opponents clustered together and to easily sneak up and eliminate them all with a single gravity hammer stroke.

An easy way to do this will be to man the turrets on the pit in a crazy king match, people in the hill will usually be to preoccupied to worry about you and you can mow them down with ease.
