Editing Speedrun

{{Status|RealWorld}}
{{Wikipedia|Speedrun}}

A '''speedrun''' is an attempt by players to finish any [[campaign]] level as fast as possible. This is done by having good understanding of the game's gameplay mechanics and exploiting these mechanics. Common methods in a ''[[Halo]]'' speedrun is by using [[explosive jumping]] technique, careful selection of weapons and bypassing as many engagements as possible, sometimes getting outside the map to do so. Allies may also be killed to skip dialogue. Halo speedruns are typically run on either Easy or Legendary, with each difficulty being a separate category. A subcategory under Legendary, L.A.S.O. (Legendary All Skulls On) requires the runner to activate all skulls while playing on Legendary. L.A.S.O. typically requires different routing from that of a no skulls Legendary run.

Due to performance limitations between a controller and mouse and keyboard (MKB), runners may prefer running on PC through [[Halo: The Master Chief Collection]] if possible.

==Terms==
* ''' "Full Game" or "Marathon" ''' refers to playing the entire campaign in one sitting.
* ''' "IL" ''' stands for "Individual level", and typically grinded for a better time in preparedness for a marathon run.
* ''' Segmented ''' runs are multiple speedruns that are edited to where only the best clips are shown. A segmented run is the quickest ''theoretical'' time.

==== [[Halo (Halo: Combat Evolved level)|Halo]] ====
# During the initial fight around the Forerunner spire, killing all the Marines despawns the fourth dropship.
# In the Forerunner cave, by jumping out of your Warthog before the wall on the right side before the bridge, the cutscene of the lightbridge appearing is skipped.
# On Legendary, most of the Marines in two of the three final areas are killed by the player from afar, leaving the other Marines to die by the Covenant.
 
==== [[The Truth and Reconciliation|Truth and Reconciliation]] ====
# By performing a [https://www.youtube.com/watch?v=CkTDQfBeUpE triple grenade jump], the player can skip a portion of the hanger fight. Subsequently, this also skips a trigger allowing the level to end early.

==== [[The Silent Cartographer]] ====
# After landing, walk in the opposite direction of the Covenant forces towards the entrance to the Security Checkpoint. Grab the Warthog and continue to the Cartographer.
# By driving the Warthog into the Cartographer facility and "flinging" your Warthog and exiting, it is possible to fly through the door as the Elite closes it, negating the need to go to the Security facility (make sure to kill the Elite after you're through).
# By jumping while going into the Map cutscene, the scene can be skipped.
# Another [https://youtu.be/B99XjCs9m6U?t=143 grenade jump] can be done to skip going back up most of the levels.
 
==== [[Assault on the Control Room]] ====
There are two variations to skip the level:
* Drop down onto the cliff below the first bridge and precariously drop from cliff to cliff until you can safely drop down.
* Lure a Banshee over to the entrance to the first bridge and force the occupant out. Enter the Banshee and continue.

==== [[The Library]] ====
By using a trick called [https://www.youtube.com/watch?v=GEE5wEJSSJQ "flood bumping"], it is possible to skip many of the doors that normally would require waiting for up to 90 seconds.

==== [[Two Betrayals]] ====
Through a bit of wiggling, it is possible to get a Ghost or Banshee past the destroyed door.
* If continuing in a vehicle, certain triggers must be activated in order to complete the level.

==== [[Keyes]] ====
Using another flood bump, most of the level, including not having to go down onto the surface and back up, is skipped.

=== ''Halo 2'' ===

A major trick, known as [https://www.youtube.com/watch?v=kTscUKqk72o sword flying], depends on the original Halo 2 version 1.0 and the game running at 30fps.
Therefore, Halo 2 Anniversary is considered a different category.

==== [[Outskirts]] ====
By using a grenade jump, the player can reach out of bounds and walk on the roofs on many buildings, skipping the first part of the level.

==== [[Gravemind (level)]] ====
By exploiting the [[Permanent invisibility]] glitch, the level is a lot easier to traverse.

==== [[Uprising]] ====
You can end the level early by [https://youtu.be/arj04MzTkAI?t=115 jumping out of bounds and navigating to a certain point.]
