50 Degree Banshee Fire

This glitch is available only for Halo: PC.

Play any multiplayer level with trees and a Banshee. Use the Banshee and shoot at a tree when it's close to you. All your bullets, including Fuel Rod shots, will barely graze the tree and shoot upwards.

Although this is possible to do with the alternate shot, or Fuel Rod shot, it is not safe because the plasma is controlled by gravity. It sometimes hits the tree and you with it.
