One Position Kill
Vacuums Enemy Players to One Position
OPK stands for One Position Kill, and is a hack where a player "vacuums" all enemy players in front of him, allowing massive kills. The hack makes every single player (who is an opponent) placed in front of the hacker (this can be only seen by the hacker him/herself, for the game is running normally on the other players' games). The hacker tends to use basic Default weapons and just Headshot all the people in front of him/her (who could be on the opposite side of the arena). All enemies would die instantly from this, causing it to be a very easy spotting hack. There is also an advanced version of this, called Zero HP OPK, or Lifetaker, by some. It functions exactly like OPK but instead, leaves enemy players on 0 HP, thus not allowing them to respawn and allowing for continuous kills, which allows scores such as 551 kills and 0 deaths on an Elimination game with the kill cap set to 140. It produces the same effect as Telekill. It is sometimes confused as "One Person Kill".
The hack originally started as public, done easily with any memory editor. Tutorials flooded public hack forums in mid-september of 2008. After a late patch, it became a staple of VIP packages. As of late 2011, almost every public hack has inlcuded OPK into their hacks, which may explain the OPK riots and constant rampages which resulted therein. This hack should not be confused with Remote Kill, even though they function similarly.
