The Cutting Room Floor research

(Differences write* Up by Dragonslayer182 from Obscuregamers.com)

  • Menu:
    • No Bungie/Microsoft startup videos.
    • Flyby of the Halo takes a different path
    • "Campaign" is split into "New Campaign" and "Load Campaign"
    • No sound.
    • The difficulty selector has different icons from the final game.
    • Main Menu has random diagram text (I don't know if it says anything, all I have is some cheap component cables on a 4k tv... not exactly a clear picture. Damn I wish I had the space for a crt.)
    • Locked level picture is a placeholder white question mark on a black background.
  • Everywhere:

    • Currently playing sounds don't stop when the game pauses.
    • Needler has full firerate immediately instead of ramping up.
    • Needler has different sound.
    • Health packs are green boxes with a white circle and red cross on them.
    • Some weapon elements disappear when invisible (Needler needles, Plasma pistol charge, Assault Rifle ammo counter).
    • Needles on needler disappear when reloading, and don't "Pop out", instead instantly appearing when done reloading.
    • Warthog engine pitch is lower.
    • Warthog wheels create sparks more often.

    • Loading screens are just a black screen with a dark red bar to show progress.
    • Plasma pistol doesn't shake while holding a charged shot
    • First person arms seem to be different behind the forearm, possibly leftover from an earlier armor design?
    • Master Chief armor is somewhat lower poly on some parts of the armor (Such as forearms)
  • Campaign:
    • Easy difficulty does not exist.
    • Green subtitles (Dialogue often differs from the subtitles, too many differences to list.)
    • Crewman uniforms are different.
    • Elites don't talk in reverse, instead speaking normal english.

    • Covenant armor is shinier.
    • Elite minors' "bodysuit" is a lighter gray. Majors seem to retain the final, darker bodysuit.

    • Sleeping grunts don't die in 1 melee attack unless whacked from the back.

    • Tank canopy is taller, closer to multiplayer counterpart.
    • Tank machine gun has assault rifle firing sound.
    • Tank explosion radius seems to be bigger.

    • Chief's armor is white if you look down while in the Crypod.
    • When you exit the cryopod, you spawn to the right of it instead of in front of it.
    • After the targeting sequence (Look at the lights so they turn green), the gameplay tip is instead a message to playtesters telling them to ask a staff member for assistance changing the controls.
    • Tutorial doesn't invert your looking pitch
    • The crewman who opens your cryopod says "Come on, this way!" instead of "This way!" when leading you out of the cryo room.
    • Elite breaking into Cryo 2's control room holds (and kills Sam with) a needler instead of a plasma rifle.
    • A crewman plays a "noticed player" dialogue and then dies is in the room where you have to crouch under the blast door.
    • The chunk of the map that's loaded for the armory/bridge/mess hall seems to have a lighting bug, possibly missing all lighting.
    • Chipps Dubbo (The aussie marine who escorts you to the bridge) has a different, non** Aussie voice.
    • Bridge cutscene triggers earlier, when you're halfway into the room instead of when you're near keyes.

    • Cortana's "hologram appearing" effect is missing.

    • Halo is not visible from the bridge windows.

    • Airlocks do not have numbers on the walls.

    • Extra room directly in front of you after the sequence where you normally watch the lifepods launch and get shot in the final game.
    • When you're about to enter the maintenance tunnels, after "Follow the maintenance accessways", Cortana says "Head near" instead of telling you to follow the nav point.
    • Maintenance tunnels softlock you, as the 3 doors near the group of covenant do not open. On heroic, the doors don't open at all. On normal, the game opens the "safe" door... by one inch before stopping.
    • Crewmen t** Pose sometimes.
    • Some (But not all) of the drink dispensers have a different texture, possibly a plate mean to close off the drink dispensers?

  • Truth and reconciliation:
    • Foehammer: "Touchdown in 10 seconds, we're in covenant territory now!" (After she drops everyone off)
    • Cortana: "All ground troops are clear of the ramp, we'll radio when we're ready for resupply"
    • Foehammer: "Roger that, moving to observation distance."
    • Cortana: "Sargeant, don't go in guns blazing. Let the chief and I scout up ahead."
    • Spawn next to pelican when leaving it
    • According to debug text, the hunters dropping onto the gravpad was supposed to be a cutscene.
    • In the ship's grav lift lobby, some covenant crates are lopsided, floating, clipping in ground, etc.
    • No sword elite in the grav lift lobby.
  • The Silent Cartographer:
    • Doors lights don't glow red when locked
    • The door hiding the gold Elite locks as soon as you enter the hallway instead of there being a delay.
    • The window in this hallway has no invisible barrier, you can jump through it.

    • Many more grunts on the starting platform
    • No sleeping grunts at the first bridge
    • Hunter in the pathway to the first elevator
    • No wraith attacking the few marines with a warthog
    • The Banshee at the first bridge is present on all difficulties, instead of just Heroic and Legendary.
    • It seems to be impossible to slide down the canyon early at the first bridge. The fall timer kicks in before you even get to the ledge. In the final game, the fall timer won't kick in until after you've bounced off the ledge.
    • The area with the small, cut out ledge under the bridge that you jump to before the attempting the slide is darker.

    • Debug text spams "YOU SHOULDNT DO THIS!!!" during the transition from the dead marine scene to the flood ambush scene.
