Yooo! Here is the video of Custom Game XP after Patch 1.08 and S & D Unlimited! Program: 500 XP / Kill / / A Prestige / Hour! I said ... Update this has not taken very long x)
You need two people to perform this glitch, both players should seek a part in advanced training / lens and leave in search AND THIS THREE TIMES, they must also load the SAME game mode (S & D unlimited).
The player who makes the Glitch must be placed in the menu "Multiplayer" and those who get to be in the "Custom Game", it must be loaded S & D unlimited, making "B" and placed his cursor to "Yes."
Whoever makes up his Glitch cursor to "Public Party" and his friend joined by "Y" by "X" and then spamming the button "A".
When you join your friend's living room, it must leave the room (it was already prepared by putting the cursor on "yes" to leave the room).
IF THE GLITCH WORKED YOU MUST IMMEDIATELY GO TO RIGHT IN YOUR PLAYER CHANNEL TO NOT FREEZE, once this is done, no more stress, you have all the time
Your friend must then RELOAD the same game mode and you reach by the menu "Custom Game".
When you joined in the lounge, you must exit and return to Custom Game, RELOAD the same mode, then you join your friend from the menu "Custom Game"
The Glitch is completed, ENJOY
