Unused Enemies#
There are a couple unused enemies that still exist in the game's data.
Banger Infection Form#
Watch on YouTubeThis is an alternate Infection Form that explodes like a plasma grenade when popped. While the model data is nonexistent, the render_model tag and reused shaders suggest it was identical in appearance to a normal Infection Form.
Shielded Flood Carrier#
This Flood Carrier variant is left over from Halo 2, but because the Jackal Shield weapon is part of the Jackal model in Halo 3, there is no shield for it to spawn with.
Unused Vehicle#
Walking Shade Turret#
Watch on YouTubeA prototype of a slow moving Shade Turret with no textures that can move on spider-like legs.
Unused Cinematics#
There are several unused cinematics that still exist in the game's data.
Video Calibration#
Watch on YouTubeA cinematic in which Sergeant Johnson helps the player calibrate video settings. A pre-rendered version of this is used in the Halo 3 Essentials disc included with the Collector's and Legendary Editions of the game. The original cinematic tags and resources are still present in the mission Crows Nest and can be played in-game with some hacking.
343 Found#
Watch on YouTubeA half-finished cinematic in which Master Chief releases 343 Guilty Spark from imprisonment on The Ark, notable for having placeholder voice over.
Ziggurat Reveal Alternate#
Watch on YouTubeAn extension on the reveal of the Forerunner tower in the beginning of the final mission, Halo. The dialog indicates that it was supposed to be a suicide mission, until Johnson showed up.
Orbital Scarab#
Watch on YouTubeAn extension of the cutscene from The Covenant in which the Scarabs drop from orbit. Presumably the camera traces the Pelican and Hornets as they descend.
Scarab Intro#
Watch on YouTubePerspective intro for the Scarab battle on The Storm.
Unused Weapon Icons#

In the sprite sheet containing the icons used for the Post Game Carnage Report, there are a few that go unused. In the final game, kills using the Power Drain fall under the category of explosions. There are also hints the return of the Halo 2 Spectre turret. Other oddities include placeholders like "Unknown15", "Unknown16". The "Mantis" listed here is not the mech that would later appear in Halo 4, but the early name for the walking Shade Turret.
"Plasma Mortar" from the PGCR sheet has an actual image in one of the game's fonts. It is meant to represent the Wraith's main cannon, but the entire Wraith icon is used in the actual game instead. It can be seen in-game using the unicode character E128.
Unused Audio#
Placeholder Dialog in Miranda's Death Cutscene#
Watch on YouTubeLeftover in the files is a placeholder VO track for a cutscene on The Covenant, though not all lines play correctly.
Cut Mission Dialog#

Various pieces of dialog that were to be used in Campaign compiled together.
Unused Settings#
Autosave Film Settings Menu#
A cut menu in which you could set which game modes can automatically save theater films. While the toggles themselves save to your profile, nothing automatically gets saved regardless of what you choose. The feature was likely cut to prevent a player from leaving it on and filling up their hard drive, or it was created early on before recent films were stored in the console's cache.
