Have Force Field mapped to a key/button, and for more force set it to 3 times the force. Create a powerful vehicle. The bigger the better. Like us_semi is awesome. The one I made is a 4WD dually. Clone it 3 times. Drive a pretty good distance away from the clones. Probably just as you see them disappear from your sight. Position yourself perpendicular to the cloned vehicles. Spawn a Crusher. It's invisible to the stupid AI and they will drive full speed into it. It will spawn to your left, which will be between you and the clones. Activate AI → Chase Me! As the clones race to you at full speed and just before they hit the Crusher, activate the Force Field. Enjoy the carnage! Lol Even the heavy Crusher cannot withstand the force of the Force Field and it fires like a bullet into the oncoming AI clones!
