To earn the Overkill Achievement in Halo 3, you must win the Overkill medal (kill four players within four seconds of each other) in a ranked free-for-all matchmaking playlist such as Lone Wolves.
Gain an overkill in free-for-all playlist
Kill 4 people within a short period of time
get the overkill achievement
head-unlock overkill achievement shoulders-unloked by default with the new update body-unlock triplekill achievement
At bare minimum: the Invert halo too. if you want a perfect fit: Empire prophecy. anything better then that is probably overkill.
no i play all the time on social playlist,rumble pit,ranked,and unranked games & i always at least get it once
To get an overkill you need to get 4 kills within 4 seconds of each other, i.e. 1 kill within 4 seconds another kill within 4 seconds another and so forth ;) easiest way to do that is in swords either lone wolves or rumble pit.
it goes doule kill, triple kill, overkill. killtacular, killtrocety and after that i don't know that's the highest i have in a kill series.... 2 kills is obviously the double kill, 3=Triple Kill, 4=Overkill, 5=Killtacular, 6=killtrocity, 7=Killamanjaro, 8=killtastrophy, 9=killpocalypse, and 10 kills is the Killionare.
