A very funny glitch that I found was this (and as followed, instructions on how to perform it):
Ok, so first you go to multiplayer and set the mode to Industrial Esponiage on the Skyrail stage and be a phoenix ninja. Then you set the al bots. The best way to do this is to make one ninja. Don't change any stats for any of the al bots. Then make the rest dominique. Set the score for 15 and the time limit to unlimited. Put grapple on for easier transportation. Any weapon set is good. (I usually set mine to random.) For something better set the vehicles to random too. Then you can start.
Now first you have to get the disk. Now, remember where you picked it up. Just remember. Now flee to the top of the castle. DO NOT RETURN THE DISK YET!
If you already did, then it's fine, you just have to get the disk again. Anyway, then wait until all the blue dots on the radar are in one spot (that does not include the big triangles). When they are, go back to where you found the disk but DONT GET TOO CLOSE!
Just peek around the corner or get a sniping view. Now all the dominiques will be running around the spot where the disk was picked up.
Now you can do whatever you want with them. It's funny because Dominique sucks in storymode and is stupid and gets herself killed. Now she just looks like a ******... with clones. What's also funny is that Ninja always tries to go and kill them all, but they all stop what they are doing and start shooting and he gets killed within like five seconds. And when he does manage to drop one, they go straight back to running around in the exact same spot. This is fun when you have a sniper. Also the vehicles are fun to destroy them with. Just be careful when you kill them in a vehicle, because they will run around getting weapons after death, and they might come across you and collect the disk. If this happens then they will stop running around. It can be performed multiple times in one game. This is a great way to trick your friends into losing all his/her teammates.
