Hmmm...
To do:
  • There are revisional differences on this game which involves graphical update between the original release and the 2010 update.
  • Document weapon_sniperrifle, weapon_flaregun, weapon_irifle, MP3 Player (Disabled features that can be found in SDK)
  • There are unused sounds that are the old Steam notifications sounds. (message.wav, friend_online.wav and friend_join.wav)

Half-Life 2 is a game where the right crowbar in the wrong hand will make all the difference in the world.

Debugging Features

Debug Menu

HL2-DebugMenu.png
The debug menu can be activated by pressing [Shift+F1], and displays a collection of multiple shortcuts to console commands. You still need sv_cheats 1 for many of these shortcuts to function correctly. The window can be closed by pressing [Shift+F1] again. Closing the window by clicking on the "X" will not disable the overlay, just hide the window.

The debug menu loads its interface from the script file "debugoptions.txt." The file uses the following format: 

DebugMenu
{
	"width"	"512"
	"height" "300"

	"<tab>" // a tab on the debug panel
	{
		"<command>" // adds a button that executes a command when clicked
		{
			"command" "<command>" // console command to execute
		}
		"<toggle>" // checkbox that toggles a cvar between 1 and 0
		{
			"togglecvar" "<cvar>" // cvar to toggle
		}
		"<increment>" // button that cycles through options for a cvar
		{
			"incrementcvar" "<cvar> 0 5 10 15" // cvar, followed by the numbers to cycle through
		}
	}
}

The menu also exists in practically all games that use the "Source 1" engine.

Unused Weapons

A number of non-player weapons have varying levels of implementation for player usage.

Alyx's Gun

HL2-weapon alyxgun-ingame.png
The gun used by Alyx (weapon_alyxgun). Can only be obtained by typing give weapon_alyxgun in the console (it must be picked up manually after closing the console, as it spawns on the ground). The viewmodel is glitched due to it using the worldmodel instead, and will block the player's vision frequently. The gun has semi-auto and full-auto modes which can be swapped with "secondary attack" button. Both modes do the same amount of damage (about as much damage as the retail pistol), but neither mode has any recoil, and both modes are about as accurate as the pistol. As noted below, there was also evidently a rifle mode planned at some point.

Picking up the gun will have it show up in 5th pistol category slot for unknown reasons. It has one full clip loaded and none in reserve, and the only known way to get more ammo would be to use the givecurrentammo command, which will max out your ammo to 150 (180 including the loaded clip). This can be increased by using the command sk_max_alyxgun #, # being the amount of ammo you want.

Annabelle

HL2 annabelle unused weapon.png
Father Grigori's rifle (weapon_annabelle). Can only be obtained by typing give weapon_annebelle in the console. It has a two-bullet tube magazine and shares ammo with the revolver. The viewmodel is identical to the retail shotgun. It does the same amount of damage as the revolver, but will only reload a single bullet when emptied. Upon reloading manually, console errors reference an incorrect call to the retail shotgun reload, and the weapon is reloaded instantly at full capacity. Despite sounding and looking like a shotgun, it fires a single bullet like the revolver, and has zero recoil.

It occupies the same slot as the AR2, and if you press 3 to select the AR2, you'll pull out the Annabelle instead. This is the only way to reequip it apart from pressing the "last weapon used" key...if it was your last used weapon.

Food Package

Half-Life 2-weapon citizenpackage-ingame.png
The food package (weapon_citizenpackage). Can only be obtained by typing give weapon_citizenpackage in the console. It has no proper viewmodel, instead using its worldmodel, though it lines up decently with how other weapons are held by the player. Comments in the weapon's coding reveal that it's a weapon because NPCs are able to carry weapons, but can not pick up or wield normal objects, so any objects the devs wanted citizens to hold needed to be coded as a "weapon". 

   // Citizen package. Not really a weapon, just needs to be a visible model for citizens to open.

Two things of note are that its pickup icon reuses the shotgun's, and that it occupies the same slot as the SMG, but it doesn't have its own selectable slot, meaning that like Annabelle, you can only reequip it if you press the "last weapon used" key or press 3 on the keyboard and then fire.

Suitcase

HL2-weapon citizensuitcase.png
A suitcase (weapon_citizensuitcase). Can only be obtained by typing give weapon_citizensuitcase in the console. It has no proper viewmodel, instead using its worldmodel which blocks most of the player's vision, as it's placed almost directly in front of Gordon's face. Like the food package, it was coded as a weapon to allow citizens to carry it around, even going as far to have the exact same comment as the food package in its coding. Also like the food package, it's in the same "slot" as the SMG, but doesn't actually show up in your weapons, and can only be reequiped using the same methods as the food package (pressing 3 will not work if you already have the package).

Interestingly, it seems to use the MP5K icon from the prototype as its pickup icon.

Stunstick

The Stunstick from the Half-Life 2 prototype kept its viewmodel, along with the early suit color. However, there is no way to wield it in the retail, as picking one up gives armor instead. Valve updated and completed this weapon for Half-Life 2: Deathmatch.

To remove the armor pickup: open src/hl2/hl2_player.cpp in the Source SDK and comment or remove the following section: 

#ifndef HL2MP	
	if ( pWeapon->ClassMatches( "weapon_stunstick" ) )
	{
		if ( ApplyBattery( 0.5 ) )
			UTIL_Remove( pWeapon );
		return false;
	}
#endif

Unused Items

Sniper Rounds

Halflife2 Sniperrounds 2.png

The sniper ammo (item_box_sniper_rounds) from the prototype was kept in the final game. It can be spawned using ent_create item_box_sniper_rounds and picked up, but no weapon in the game uses this type of ammo. It also has no physics, but will still produce bullet holes if shot at. The original box texture has been replaced with a pink texture saying "OBSOL33T" (obsolete in "leet speak") in cyan letters. Why it wasn't just removed outright is unknown.

Flare Rounds

Hl2-boxflares-mdl.pngHl2 flarerounds.png

Flare rounds (item_box_flare_rounds and item_flare_round) still exist in the final game and can be spawned with ent_create item_box_flare_rounds/item_flare_round, but cannot be picked up due to the ammo coding having been removed. However, the console will give constant errors stating that it's attempting to give the player an unknown "FlareRound" ammo type as long as they player stands over them. Like the sniper rounds, neither of these have physics but will produce bullet holes if shot at.

Unused Animations

Careful, you'll lose an eye.
This page or section needs more images.
There's a whole lotta words here, but not enough pictures. Please fix this.
Specifically: Get animations of these things in action if possible.

Weapon Animations

Alyx's gun has unused animations that show it transforming into a SMG and a rifle. However, no idle animation for these modes exist. In addition, Alyx herself has animations for changing the pistol into an SMG, and the SMG to a rifle, but not back to the pistol or directly to rifle mode.

Used Unused

  • Pistol variation.

  • Rifle variation.

  • SMG variation.

Firing Animations

  • The Combine soldiers possess an unused firing animation for the HMG1 as well as animations for placing and rolling grenades.
  • The poison headcrab has an unused animation, depicting it spitting something from its mouth, most likely poison. There is no data about the fired projectile or its effect on the player however.

Struggling Animations

Vortigaunts have unused animations for being grabbed by Barnacles, reminiscent of the behaviour of human NPCs in Half-Life. However, these go unused, as they are instantly killed and turned into a ragdoll upon being strangled by one, like all other NPCs. In addition, game files mark such events as "legacy content".

Leftover Citizen Animations

Due to how animation files are shared between models, key NPCs like Breen and Alyx have access to all of the regular animations despite only using a few.

  • Breen reloading a pistol, despite not normally being shown to do so in the retail game.

  • Father Grigori healing. By default, only Medics can do this. In addition, he also has lines for giving healthkits and ammo.

  • Alyx holding an SMG. She normally only uses her own pistol and a shotgun in Episode One.

Unused Textures

Dummy Texture

Half Life 2 Dummy Texture.png

A dummy texture can be found in the engine folder of hl2_textures_dir.vpk.

breen_fakemonitor

Half-Life 2 PC Breen fakemonitor 00 00 00.pngHalf-Life 2 PC Breen fakemonitor 01 00 00.pngHalf-Life 2 PC Breen fakemonitor 02 00 00.png

An unused 3-frame placeholder animation for the City 17 screens, named breen_fakemonitor_.vtf.

Snow & Ice

  • HL2 snowfloor001a.png
  • HL2 snowfloor002a.png
  • HL2 snowfloor003a.png
  • HL2 snowwall001a.png
  • HL2 snowwall002a.png
  • HL2 snowwall003a.png
  • HL2 snowwall004a.png

A set of snow and ice textures that don't seem to be used anywhere. They do end up appearing in Mossman's transmission in Half-Life 2: Episode One.

matsys_regressiontest/background

Hmmm...
To do:
Whose cat is this, though?

HL2-matsys regressiontest-background.png

Inside an inconspicuously named folder is this picture of a cat. This is probably the most well-known unused texture from Half-Life, due to how frequently it crops up in various Garry's Mod miscellany.

This texture was apparently meant for regression testing while they were rewriting the materials system for The Orange Box, and somehow it made it all the way into the final release.

Prototype HUD Leftovers

The HUD and weapon icons from the prototype still exist inside the game's files. The final game instead stores the weapon icons in fonts. There are also graphics for Half-Life weapons scattered around, intended to be used for its Source engine port, Half-Life: Source.

Hydra

Spinal Cord
The Intestine
The Bottom Intestine

The textures for the cut Hydra lies in both the effects and sprites folder.

boxrocket_chell_head

Hmmm...
To do:
Texture/texture on model comparison with used version.

Seems to be for an early version of Portal's Chell's facemap. There are no models to this, only textures. "Boxrocket" is the codename used for the Source Filmmaker, which had been released with the TF2 update Meet the Pyro in 2012.

This is not present in the 2004 retail version, but was added when Portal was released.

dev

Hmmm...
To do:
Are any of these textures also unused? (From the same folder, filenames are exactly the same as in the folder minus the HL2 prefix)

There are a number of development-related textures in the dev folder, along with several unused textures for things like brick buildings and signs.

Unused Models

Gordon Silhouette

A weird, chrome-textured "silhouette" model of Half-Life Gordon can be found. It was clearly not meant to ever be seen in gameplay as it is more or less a statue, possibly used for referencing where the player would be standing. Can be seen via thirdperson command.

  • Gordon

props_c17

Half-Life 2-props c17-chair02a.png

models/props_c17/chair02a.mdl

ARR! Camera

TF2 Camera.png

A lightly rebranded Arriflex 435ES movie camera with a highly detailed model. Also exists in Team Fortress 2.

shaderslab

HL2 shaderslab2.png

In the shadertest folder, there are five identical models called shaderslab1-shaderslab5, each with different textures. It is, as the name implies, a slab used to test shaders on.

perftest

The perftest folder contains a few resources, mostly from the original Half-Life, that were used for testing.

gman.mdl

HL G-Man. His original animations exist. This model and his animations can be found in Source Filmmaker, in the same directory.

Some textures inside the gman folder are earlier textures that don't seem to exist in Half-Life.

  • gman_face1.vtf

  • gman_pants1.vtf

  • gman_shin1.vtf

  • gman_suittop1.vtf

  • gman_suittopbk1.vtf

grass_tuft_001.mdl - grass_tuft_004d.mdl

grass_tuft_001.mdl - grass_tuft_004d.mdl are missing their textures. They're supposed to be grass tufts, hence the name.

loader_static.mdl

The Loader. Original animations also exist.

null.vtf

An unused "null" texture found with the Loader's textures.

  • rocksground01a.mdl

  • rocksground01b.mdl

  • rocksground01c.mdl

  • rocksground01d.mdl

  • rocksground01e.mdl

  • rocksground02a.mdl

  • rocksground02b.mdl

  • rocksground02c.mdl

A bunch of different rock pile variations also missing textures.

wall_section10k.mdl ground_objects8k.mdl

wall_section10k.mdl, wall_section10k_halfsize.mdl, and ground_objects8k.mdl are high-poly test models. These were also used in the map devtest_highpoly.bsp in the Android port of Half-Life 2 released for the Nvidia SHIELD.

  • babtech_bordl9.vtf

  • con1_bord04.vtf

  • dirtfloor006a.vtf

  • fifties_dr4.vtf

  • fifties_dr5d.vtf

  • fifties_dr6.vtf

  • generic031c.vtf

  • out_grvl2b.vtf

  • rock_wasteland01a.vtf

  • rockcliff02b.vtf

  • rockground03a.vtf

  • rockwall002a.vtf

The rest here are world textures.

Unused Model Features

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Look at other weapons/models in the Model Viewer and see if they have unused/unseen features or elements.

SMG Magazine Bone

Unused model bone selected in a model editor.
The model for the SMG contains a magazine bone (ValveBiped.clip) that, as expected, moves the magazine. Despite this, the magazine is never animated during the reload animation in-game, with Gordon instead just smacking the bottom of the clip. Based on the fact this section of the model has been weight painted, it's likely this was meant to be animated at some point, likely being scrapped since you never see that far down when reloading anyway.

Vortigaunts

Vortigaunts have a ton of unused dialogue for fighting alongside the player in a squad. They cannot join player squads in the final game, even when spawned by the player or placed in custom maps. Some of these lines were reused in Episode Two, albeit mostly being re-recorded with the new Vortigaunt voice actor, Tony Todd.

"Drivable" APC

Halflife2 apc.png

At one point, APCs were intended to be controllable by the player, but playtesters ultimately felt it was too slow compared to the buggy, and this function was cut. But there are remnants of this left in the game, as it's actually possible to enter an APC pretty early in the game.

In d1_trainstation_03 (the level where Gordon meets Alyx for the first time), two APCs can be seen driving around on the street, eventually veering off into an alley (there's another APC near the opposite end of the map that can't be interacted with). Using god mode, the player can jump down to the APCs and enter them like any normal vehicle...but the camera will be completely screwed up and the player can neither drive nor exit the vehicle, requiring them to reload a save to get out. The APCs can not be entered before they stop moving, likely due to the quirk of Source requiring a separate NPC (npc_apcdriver) to actually make them move and shoot, so when the APCs are in the alley, this effectively means the NPC has exited the vehicle.

Also of note is that the controls for the buggy will show up upon entering it.

Alternate Intro

E3 2004 (intro.bsp) Final (d1_trainstation_01.bsp)

Loading the map intro.bsp via the console will bring you to a slightly different version of the game's intro. The main differences between the two intros is that there is no title card at the beginning, missing textures around the Spectrometer that they were replaced and removed during development, and a view of the railway which was seen during E3 2004 as opposed to the prison near the end of the game. G-Man is also slightly off center during his final line.

intro.bsp doesn't end due to the respective level change trigger not existing. This ultimately suggests that the intro was originally going to be its own separate map rather than being a part of d1_trainstation_01. This was probably removed to avoid creating another loading screen between the intro and gameplay. A similar approach was attempted and scrapped during Episode One and Two's developments.

Soundscripts

game_sounds_physics.txt
Curiously, some "test" sounds exist inside this soundscript file. Only the music file (hl2_song1.mp3, Particle Ghost in the soundtrack) is present and can be used, since the sines aren't included in the sound files, but they do exist in the prototype.
