Editing Cut Halo Online levels

{{Series/Cut/HO}}
Due to the cancellation of ''[[Halo Online]]'', several multiplayer maps and a single-player training scenario were cut from the game. The map data is largely gathered from the files of the MS30 build of the game, wherein map names and descriptions can be found. Some map files have the prefix <code>s3d_</code>, indicating the map was built for the [[Saber3D engine]] employed by [[Saber Interactive]] and is thus built wholly new for the game. Other maps returning from prior ''Halo'' games do not have this prefix, indicating they were to be 1:1 ports. 

This page lists only maps which never made it into a publically-accessible build of ''Halo Online''. For a list of all other ''Halo Online'' maps which did make it into the playable builds, see [[:Category:Halo Online multiplayer maps|here]].

==Tutorial==
Named <code>s3d_tutorial</code> in game files for the MS30 ''Halo Online'' build, this level would have been set on [[Anvil Station]], and serve as an introductory tutorial for new players starting the game. Several pieces of released concept art for the level indicate the level was to involve a shooting range and [[Covenant]] automated turrets.

==Multiplayer maps==
===Cold Storage remake===
{{Article quote|The [[Swords of Sanghelios]] have not shared the reasons for their interest in this seemingly abandoned logistics base.}}
Named <code>chillout</code>, little is known of this map aside from its name and description. The description suggests this map would be a [[Covenant]]-themed remake of the maps [[Chill Out]] and [[Cold Storage]]. Some related text strings indicate this map may have been intended to be called "Abeyance" in the final game.

===Drydock===
{{Main|Drydock}}
{{Article quote|The docking spires on High Charity serviced vessels from a hundred worlds and a dozen species.}}
Named <code>s3d_dry_dock</code> in the MS30 build, this map's description indicates it would have been set on [[High Charity]]. Several pieces of released concept art, shown below, were named "drydock" and may be for this level.

===Lockout===
{{Article quote|The creatures once imprisoned here are content to wait in the void of space for uncountable years.}}
Named <code>s3d_lockout</code> in the MS30 build, this map was presumably a remake of the ''[[Halo 2]]'' map [[Lockout]]. Concept art has been released for this map, depicting a possible setting similar to the map [[Haven]] on [[Requiem]].

===Powerhouse remake===
{{Article quote|Powerhouse is set in a hydroelectric facility on planet Reach formerly utilized to provide alternative power supply to the rural settlers nearby, but was repurposed to support the military war efforts.}}
Named <code>s3d_powerhouse</code> in the MS30 build, the map's name and description suggest this would be a remake of the ''[[Halo: Reach]]'' map [[Powerhouse]].

===Sky bridge===
{{Main|Sky bridge}}
{{Article quote|Seongnam's state-of-the-art clinics and labs contain knowledge worth dying for.}}
Named <code>s3d_sky_bridgenew</code> in the MS30 build, this map was to be set in Seongnam, [[Korea]].

===Waterfall===
{{Main|Waterfall}}
{{Article quote|The UNSC constructed many secret holdfasts during the final years of the Covenant War.}}
Named <code>s3d_waterfall</code> in the MS30 build, little is known of this map. Several released pieces of concept art with the name "waterfall" in their filenames have been released and likely correspond to this map, shown below. Some text strings indicate this map may have been intended to have the final name of "Whiteout".

The map has been implemented into the ''[[Halo 3]]'' component of ''[[Halo: The Master Chief Collection]]'' in [[Series 6: Raven]].{{Ref/Site|Id=LovelyLetters|URL=https://www.halowaypoint.com/en-us/news/lovely-letters|Site=Halo Waypoint|Page=News: Lovely Letters|D=12|M=02|Y=2021}}
