So this guide has been up for awhile, and gotten a lot of support (Thank you all by the way ^w^)
but there are a few things id like to state.

One: This guide is outdated. Id recommend checking out The Cutting Room Floor instead if you are interested in the cut content of HDtF.

Two: This guide was reuploaded to another website without my permission. The only place you can find my guides is on steam, if you see my steam guides on any other website it is unauthorized.

The thing that really annoys me about it is that while yes they did credit me it was worded in a way to sound like i made this guide for they're website which i didn't. On top of that the website was filled with ads meaning they were profiting off of my work.

Lastly: I've lost a lot of motivation for writing these. While i don't really want to give up on this guide, id still say you shouldn't count on me updating it.

Thank you to Tehcooler for making me aware of the website in question.

the sig552: a weapon that was most likely going to be used in Black mesa









the Gasmask: was likely used for a starting animation.
Update: m3sa stated that it was meant to be used to protect Mitchell from nerve gas.









m67 grenade: unused due to bad coding
Update: It was added back into the M3sa build.









m240: Another secondary weapon that goes unused. it has no model.








the oneshotbarrel: only has a arming animation. works better in earlier builds. most likely used in act1
Update: it can be fired with the console command "shotosweapon"









ak47 in act 2: it has a model for it.

A map based on the demo. its a under ground rebel base.

it was A: a part of the antlion cave that got cut
As seen with this door possibly leading to it.

antlion cave. by the exit:








rebel base at the start:










something that provides for evidence for that is that its named A3C4P2 implying that it was to come after the Antlion cave
(the Antlion cave being named A3C4P1)

Antlion cave ending:









Ending to the Rebel base:








Or B: it was replaced by the Antlion cave, having its assets being reused for the antlion cave.
some examples of this theory:

A hole that looks like it could have been the spawn/way of getting in. its also right next to the current spawn.








as seen in the rebel city the way of getting into the antlion cave is just like this.










Why was it cut?: A: the map maker may have opted out,
or B: due to the game being rushed the map never ended up getting added.

What was it?: most likely a extension of the antlion cave.

Misc: some of the map uses the 2016 demo as a base. (Could be part of why it was cut)
Mitchell has custom voice lines for the map.
The map was noticeably down graded in the m3sa-beta build, meaning that there were no attempts to restore the map.

UPDATE:

A unused map that was replaced Combine base raid in the final game.









Why was it cut?: It is unknown why it was cut.
Misc: Generally the map is a harder, less rushed version of the Combine base raid.
There is something very uhh... "interesting" about it that i will get to later...
There is a closet in the map that kills you when you step in it (or noclip in it).
the map makes more sense with context of the second to last level.

UPDATE: if you spam click on the closet it will open.

Joke maps:
dev_ending.bsp

a map where the player fights young Adam in a tank. this would be very out of character for him.










Test maps:
m3sa_gun_test - a map where the player plays as a spy and kills some enemies.
dev_test_course - a map that tests a few things. most notable, a unused combine camera.

in the ending of Act 2 there is a cutscene that is men't to play, but doesn't due to bad coding.
It is in the m3sa build if you want to see it.

The player was men't to fight black ops in black mesa.

There is a unused character named "winter survivor"
possibly a character the player was men't to be helping and or be helped by.













the player can also see under the HECU's Mask, they look like a younger version of Mitchell








there is an unused texture for the Combine synth that gives it brown colored armor, this may have been used as a synth equivalent to the combine elite, or shotgunner.








There is an unused model of a Zombie metro cop, it would have fit very well with Act 3. You can spawn it with the name "NPC_Zombie_Police"

VR was planed. but then removed.

unnamed Woman - Beta Sasha: unnamed Woman is the female character seen in the beta trailer, some people also think they may have been named Jaden, most likely played the same roll to the plot.














Morgan - Beta Mitchell: he is basically the same as Mitchell But way more of a hard ass.
has the ability to read minds, given to him by the Vortigaunts or Gamer Man.

















according to D-Stri/Allon Keller he was still mostlikely men't to be Shepherds Brother.

Originally posted by D-Stri:

AS FAR AS I CAN TELL, yes, Mitchell was always supposed to be Adrian's brother, but this is the kind of plot point that Jaeger didn't talk about? .

Father Grigori: Mitchell was men't to fight(?) Father Grigori after Escaping "The Raven" This is shown in a trailer (as seen in the example Videos Section)










D-Stri/Allon Keller on Why he was cut:

Originally posted by D-Stri:

As for Grigori, I have no idea why he was removed from the plot. It might have something to do with the push they seem to have made towards excluding as many canon characters as possible? So far as I can tell, G-Man is the only real canon you meet in HDTF, right? Didn't they change Gordon Freeman into a red herring?

Smug bastard - Beta Boris: Boris but he looks like more of a business man, i bet Mitch would have had a different way of meeting him.



















Beta combine: in the beta there where more types of 7 hour war combine. also the combine bled jizz.
Most of them are from this.

Sarge - Beta Roosevelt: A generic Captain. is seen fighting the hydra in the trailer, was most likely killed in the same scene.

The Voice actor on weather or not he would die in the next scene:

Originally posted by D-Stri:

Dunno. Don't think so. From my understanding, Sarge was supposed to be the Revolver Ocelot analogue. Hense why Jaeger asked me to do my best old ocelot impression rofl.

Beta Nick, and Adam: Still Yes men, Adam most likely wouldn't have "betrayed" Mitchell/Morgan.

It is generally the same but with different characters.

D-Stri/Allon Keller stated when asked that, in the original plot Mitchell/Morgan
would hunt the down the freeman

Originally posted by D-Stri:

From my understanding, originally, yes.
Including Gordon Freeman's face in the original trailer wasn't supposed to be later used as a bait-and-switch. It was in the original plot, that Morgan would hunt down Gordon.

Wolfcl0ck says in the description of his A3C8P2 video that Mitchell was men't to die in A3C8P2, with cremators storming the house after Mitchell fended off the combine.

In the beta Mitch was meant to help with the capture of Eli Vance as shown in the trailer, and stated by Frank.

wolfcl0ck - stuff about the beta ending.
Terrors - the console command to shoot the oneshotbarrel
D-Stri/Allon Keller - semi confirmation about the beta ending, misc things about the beta.
M3sa - stuff about unused content.
