Halo 2

Halo 2 is one of the more technical speedruns in the series. With the addition of glitches such as sword flying and sword canceling, movement in Halo 2 is much faster than Halo 1. However, its glitchiness can also work against you, as there are several run-killing glitches that can occur.

Halo 2 legendary is absolutely brutal. It is recommended that you be familiar with both the speedrunning tricks and casual play on legendary before attempting to speedrun it.

Halo 2 is mostly identical between NTSC and PAL, with the exception of one clip on Oracle that saves about 10 seconds on PAL. You should run the 1.0 version on 360 to reduce lag, and for the smaller controller (helps swordflying). Halo 2 Vista (the PC version) is slower due to sword flying being patched, and the addition of loading screens between levels. However, it should still be possible to get a sub-1:35 time.

Movement Techniques

Sword Flying

335 px

Sword flying lets you lunge towards enemies across long distances. Unlike the normal limit on the sword's lunge distance, sword flying allows you to cover vast distances at high speed.

via scurty:

First off, you need to make sure you have two things: The Xbox Live update NOT installed and a sword with another weapon of your choice.

Sword flying is a simple three button combination that is quick to master because it has a rhythm to it. The button combination goes in this order: (Y) (X) (Right Trigger) The first two are hit in rapid succession (usually by the sliding of your thumb) while the third button is hit slower than the first two are spaced apart. Watch the video to hear how it sounds.

Your reticule must be red for this to work on your gun when you switch to your sword (by pressing Y). You also don't have to be zoomed if if you don't want to, although in most cases you will be zoomed in.

Most people find it easier to swordfly with an Xbox 360 controller than with an Xbox controller. To swordfly with one hand, slide your thumb from Y to X, then press R. Alternatively, you can swordfly while clawing by rolling your index finger from Y to X, then pressing R with your middle finger. This allows you to aim while preparing to swordfly.

If an enemy is standing still, you will be able to swordfly over its head and past it. If it is moving, the swordfly will stop when it is above the enemy's original position.

The Rocket Launcher is one of the most useful weapons to swordfly with, because it has a large reticule and 2x scope, and turns red at fairly long distances without much aiming.

A good way to confirm if you're pressing the buttons quick enough is to temporarily leave out R and watch the crosshair; if the crosshair turns red when you've switched to your sword, then you're doing it correctly.

Sword Canceling

Sword canceling is a movement technique. In its simplest form, sword canceling is the ability to "cancel" the effects of a sword lunge. If you press R to lunge, you can press X (Reload) to cancel the impact of the lunge any time before it hits.

This can be utilized to travel long distances in tight quarters. To swordcancel past an enemy, press R+X+A simultaneously (Fire+Reload+Jump). R+X will perform the sword cancel, and jumping will make you rise in height as you lunge, thus letting you fly through the air.

To swordcancel over an enemy's head, press A, then R+X+A simultaneously. The first jump gives you height to get over the enemy.

Ghost Quick Turn

While boosting in a Ghost, hold A to lean back and raise the nose of the Ghost. This lets you turn more sharply while maintaining your boost. It also makes you prone to flipping, so be careful.

Superbouncing

Superbouncing is a variation of a pressure launch. If the player model intersects with the geometry, the game will apply a large amount of force to try and push the player out. By going into auto-crouch, you can glitch the player model. Then when you jump on a polygon seam, you will intersect, and the game will push you out. Superbounces differ between PAL and NTSC, because different framerates means different intervals for collision detection.

The only place superbouncing is useful is as a method to board the Scarab early in Metropolis.

On Legendary, this trick saves a ton of time if used on Gravemind or another combat-heavy level.

Double Shot

By pressing Fire twice and then Reload (RRX), you can fire two Battle Rifle bursts in quick succession. The timing of

You can chain together doubleshots by tapping YY to switch away and back to the BR. With the right timing, you can double shot until the clip is empty - RRX YY RRX YY etc.

Double Grenade

Fire a plasma pistol overcharge. When the overheat bar is at halfway, quickly tap L twice. You should throw two grenades in quick succession. This is useful for some launches, such as the Delta Halo Ghost launch.

You can also double nade with a beam rifle overheat, but the timing is different.

Double Melee (H2)

In addition to the BLB method from Halo CE, you can also do BXB or BYB to melee twice in quick succession. It's not as useful for speedrunning due to the low melee damage of Halo 2 1.0.

Quick Reload

After a certain point in the reload animation (usually after the clip is in the weapon), the weapon counts as reloaded. At this point, you can cancel the rest of the animation by pressing YY to quickly switch away and back to your main weapon. If you are only carrying one weapon, you can melee and hit X to cancel the melee.
