Okay my friend and I found this really funny glitch in multiplayer. First you have to go to multiplayer and go to raptor. Then you can have one or two computers as raptors and you and any other amount of people on your team as cavemen. Get the knives or crossbow(knives work better) and hide under the frying pan. If you do it correctly you will be under the frying pan but not touching the fire and when the raptors try to get you they can't. Then you can throw knives or hit them with a crossbow and they will usually jump into the frying pan and kill themselves! I killed two raptors on einstein by myself! This glitch will always work if you do it correctly.
