Sword hijacking

Sword Hijacking is a trick that will allow you to hijack enemies in vehicles from a slightly greater distance in a map, and at a faster speed under normal circumstances. It requires perfect and faultless timing and a Covenant Energy Sword.

Walkthrough
This technique is simple enough. Merely perform a Sword Cancel (by holding down the "X" button as you lunge) towards an enemy vehicle. Continue to hold down "X" while lunging, and you will automatically hijack the vehicle when you get near it. This; is particularly useful for boarding enemy Scorpion Tanks, Wraiths, Banshees, and Ghosts. It is even more useful in multiplayer.

Note: This only works in Halo 2
