Multiplayer Glitches

Background
This is a list of glitches in Red Dead Redemption multiplayer, namely Free Roam.

Elevator Glitch
In Bonnie MacFarlane's Ranch, go to the question mark. You will see a outhouse if you go around the left corner of the house the question mark lies on. Next to it is a stack of wooden logs, go to it. Repeatedly tap R1 and you will eventually jump higher than the Redemption Mountains! NOTE: You will die once you land.

Multiple Mounts Glitch
A useful glitch if you have the best mount of all the people in your posse and feel bad for a posse-mate(s) who has a bad mount. Whistle for your mount, tell a posse-mate to mount it, and whistle again. A second mount will spawn. This can be repeated for the good of everyone in your posse.

Antimatter Character Glitch
You must have a posse of at least 2 people, a wagon, and one player needs a mic. Bring a wagon to your posse-mate or vice versa. The one who wants out of the map must be next to the driver's seat, NOT the ride shotgun seat. The player shoots the other in the head (You must score a kill) and press Y/Triangle to enter the driver seat within 2 seconds of the betrayal. Then stay in the seat. The other goes next to the seat. On a count of three, both people repeately mash Y/Triangle until a player hijacks the seat and the other gets out without being hijacked at the EXCACT same time. The guy who got out will walk through any interactable object and if he jumps off a cliff he instead walks on thin air, but can't whistle for a mount (the game says the area "is not open enough" and the mount "can't find you.") You can get cheap snipes with this glitch or take a look at the beautiful landscapes of all three territories. This glitch is "cured" by dying.

Get In The Back Of A Wagon!
Requires a wagon, and at least two players. One player finds a wagon, hijacks it, then makes the wagon stay stationary. The other player will whistle for a mount that CAN jump. He make the horse leap into the back of the vehicle, and dismounts and kills the horse. Then the driver can drive around but he should follow two simple rules, the first - stay on the road, and the second - don't go too fast.
