if you want random players you can go to trueachievements.com and search contract killer it will show every person that is registered to the game that has at least one achievement.
Only thing is alot of those people are achievement whores but normally friendly
Contract Killer Level 20 now, add me for some bro love. Sad thing is the game keeps on hanging on me and really don't wanna reinstall coz every progress would be lost. Anyways still hanging onto it, it's a tough game with difficult achievements. GT is kenzibit.
