Entry location: Anywhere in Vesus mode, on a FLAT wall.
Ok, well, to start out, bring at least 1 type of grenade, and sticky cams. To start, shoot a sticky cam at a wall. bring out your gun, and charge up a grenade (Hold L). Now, keeping L help, push in the Left thumb stick to bring out your weapons menu. Walk up to the sticky cam with Both L held, and the L-Thumb stick in. Now, when you see the "Remove" button, press whatever button your sticky camera is on, then let go of the Left Thumb stick and walk back, keeping the L trigger down. Now, simply walk up with the L trigger down, and press "Remove" and a soon as you press A, about 1 Millisecond after you press A, let go of the L trigger. You should now be in a sticky cameras view. press B to escape the stick camera and run around like a spaz. Note: This is an advantage, because when you hang off a ledge, your hands stay down, and the merc can't see your hands! It looks hilarious becuase you pull him over with you head! The Draw back is your aim is all screwed up, so you cannot shoot. To escape "Retard Mode", just get knocked over, preferably by your partner.
