How it works:
1: Accept a party invite in death match from a guy you're fighting right now.
2: Pick "Join party and game" instead of just "join party."
3. The game will ask you "are you sure you wish to leave this game?" Select "no."
4. That's it.
What does the glitch do:
The game gets confused and you end up making like 5 clones of yourself in a match. The clones will look up in the air and they will start spinning around wildly spread out across the map.
If you look at the scoreboard, you'll see your gamer tag twice up there. You can shoot yourself and get points. YAH! More achievements!
I asked the party members "look at the scoreboard, there's two of me up there!" They didn't see it.
The glitch got annoying, and I thought it wasn't fair, so I quit and restarted the match. It went away. I wish I had a dazzle to record this, but I don't have 75 bucks.
Weird glitch huh?
So what was the first glitch in a game you discovered by yourself? Me... I found a glitch in Sonic 3, which I had know idea how I did it. What about you?
