Kill Playboy X if you want to get 100%
When you kill Dwayne you don't get anything good, but if you kill Playboy X you get new house
If you kill Dwayne you won't get anything good..
Kill dwayne and Playboy X will call you to say that since you killed a former friend he wont be a friend to you any more..
If you Kill Playboy X you will get his condor as a safehouse, and you will get dwayne as a friend and can use his special feature "Calling Backup"(3 or 4 guys come to your Aid with eigther the Low level machine gun or The AK-47, i even had 2 guys show up with a M-16 and a RPG.)
P.s.
Personally i would kill Playboy X even if i diden't get the Safehouse, as dwayne allready have paid a high price to playboy X(Prison)
