Assassin Achievement

Hint by viperxsniper on February 28, 2007  |  report this hint

In order to get the "Assassin" achievement, you have to kill an opponent who has the achievement. There are two ways you can get this:
1. Get a friend that has it to play a game with you
2. When you go into a lobby, check everybody achievements and see if they have it. If not, back out of the lobby and go to a new lobby until you find someone with it. Once you found someone, make sure you are on the other team and remember the name and go for the player immediatly. If you are playing an unranked match just ask the person with it and usually they will just let you kill them so you can get it.
