Charging Needler glitch

This glitch only works in Halo 2 on the level Sacred Icon. It is the only level where Jakals appear in-game as allies.

On the level Sacred Icon when you find the Jackal and Grunts at the beginning, destroy all the Sentinels and the Sentinel Launchers to stop any Sentinels from coming out. If the Jackal is charging his Plasma Pistol after the battle, switch it with a Needler. If done right, the Needler will fire but no needles will come out. Try it with some other weapons like the Plasma Rifle or any other weapons you can find. If you give him the plasma rifle, he will fire and overheat it.
