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

Hmmm...
To do:
A whole lot:
  • Various models have unused features not seen in gameplay when loaded into an editor/viewer.
  • There are revisional differences on this game which involves graphical update between the original release and the 2010 update.
  • Prototype's HUD weapon icons are still in the game files.
  • The old HUD design is still in the files as well.
  • The "dev" folder in the textures folder contains a ton of unused textures, including some really old brick, metal, and sign textures.
  • ShaderTest folder is filled with unused testing models.

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 NPC-only weapons have varying levels of implementation for player usage.

Alyx's Gun

HL2-weapon alyxgun-ingame.png

Alyx's gun (weapon_alyxgun) can be spawned, (manually) picked up and used as its semi-automatic mode, although there is no viewmodel for it, using instead its worldmodel. It uses its own ammo, whose maximum can be set via a special console command, even though spare ammunition cannot be obtained.

Hmmm...
To do:
In-game testing about its specs.

Annabelle

HL2 annabelle unused weapon.png

Father Grigori's rifle (weapon_annabelle) can be spawned, picked up and used. It reuses the shotgun viewmodel, and uses the retail Colt Python ammo, with a two-bullet tube magazine. It possess the same damage output as the Python, however, if emptied, the game only reloads a single bullet. Upon reloading manually, errors about an incorrect call to the retail shotgun reload can be seen, and the weapon is reloaded instantly at full capacity.

Food Package

Half-Life 2-weapon citizenpackage-ingame.png

The food package (weapon_citizenpackage) can be used as a weapon, even though it has no fire mode. It has no viewmodel, instead using its worldmodel. Comments in the weapon's coding hint that it's a weapon because NPCs are able to carry weapons, but not ordinary objects like this, so anything they need to be able to pick up must be made into a "weapon". 

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

Suitcase

The first two citizens you see have suitcases that can also be spawned, similar to the food package. Its entity name is weapon_citizensuitcase)

Stunstick

The Stunstick from the early Half-Life 2 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. This weapon was recycled for several mods, albeit with different graphics. Valve updated and completed this weapon for Half-Life 2: Deathmatch.

Unused Items

Sniper Rounds

Halflife2 Sniperrounds 2.png

The sniper ammo from the prototype was kept in the final, but it cannot be picked up and has no collision data. The box texture wasn't present in the prototype either, and was re-used in Garry's Mod as one of the Material options.

Flare Rounds

Hl2-boxflares-mdl.png
Hl2 flarerounds.png

These flare rounds (item_flare_round and item_box_flare_rounds) still exist in the final, but cannot be picked up due to the ammo coding having been removed, only the entities were accidentally left in. Models and textures still exist, suggesting the flare gun wasn't entirely cut in favor of emergency flares in Episode One.

Unused Animations

Unused Weapon Animations

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

Used Unused

  • Pistol variation.

  • Rifle variation.

  • SMG variation.

Unused Firing Animations

  • The Combine soldiers possess an unused firing animation for the HMG1.
    • Two others are for placing a grenade, and rolling it, respectively.
  • The poison headcrab has an unused animation, depicting it spitting something from its mouth. There is, however, no data about the fired projectile, or its effect on the player.

Unused Struggling Animations

Vortigaunts have unused animations for being grabbed by Barnacles, reminescent 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 able to do so in the retail game without modifying Combine Soldiers or placing Unique-set Citizens with custom models in custom maps.

  • 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 Model Features

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, and instead has the player smacking it. One can assume from the fact this section of the model has been weight painted, that it's very likely this was suppose to be animated.

Unused Sounds

Hmmm...
To do:
There's most likely more than this to cover.
Sound File Filename Notes
ambient/atmosphere/
city_beacon_loop1.wav
ambient/machines/
city_ventpump_loop1.wav
hl1/ambience/
computalk2.wav Half-Life leftovers.
port_suckout1.wav
test/temp/soundscape_test/
cabin_ambience.wav Rather odd soundfiles for testing soundscapes.
cabin_wall.wav
outdoor.wav
tv_music.wav

Unused Dialogue

Citizens and Vortigaunts have unused dialogue when being shot by the player. According to the unused files, Vortigaunts could even retaliate.

Hmmm...
To do:
Upload sounds

Unused Feature

Halflife2 apc.png

It's actually possible to enter an APC, despite none of them being accessible to the player during normal play. The player will end up seeing to the right of the APC, at ground-height, and may tilt its viewpoint towards the right, sound will be muted unless you pause the game, unable to perform any actions other than pausing. Advices for the retail Scout Car pops up to the right upon entering the APC.

Unused Models/Textures

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.

Half Life 2 Dummy Texture.png

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

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.

Early HUD Icons

Weapon icons from the prototype still exist inside the game's files. The final game instead stores them in fonts. There are also graphics for Half-Life 1 weapons scattered around, intended to be used in its port to the Source engine called Half-Life: Source.

ARR! Camera

TF2 Camera.png

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

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 Meet the Pyro in 2012.

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

perftest

The perftest folder contains a few resources, mostly from Half-Life 1, that were used for testing.

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

gman.mdl

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

grass_tuft_001.mdl - grass_tuft_004d.mdl

The Loader. Original animations also exist.

loader_static.mdl

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

  • null.vtf

A bunch of different rock pile variations also missing textures.

  • rocksground01a.mdl

  • rocksground01b.mdl

  • rocksground01c.mdl

  • rocksground01d.mdl

  • rocksground01e.mdl

  • rocksground02a.mdl

  • rocksground02b.mdl

  • rocksground02c.mdl

wall_section10k.mdl, wall_section10k_halfsize.mdl, and ground_objects8k.mdl are high-poly test models. These appeared in the map devtest_highpoly.bsp in the Android port of Half-Life 2 released for the Nvidia SHIELD.[1]

wall_section10k.mdl ground_objects8k.mdl

The rest here are world textures.

  • babtech_bordl9.vtf

  • con1_bord04.vtf

  • dirtfloor006a.vtf

  • fifties_dr4.vtf

  • fifties_dr5d.vtf

  • fifties_dr6.vtf

models/props_c17/chair02a.mdl

Half-Life 2-props c17-chair02a.png

Hydra

The IntestineThe Bottom Intestine

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

Spinal Cord

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. Maybe they had something to do with the Borealis? They do appear in Mossman's transmission in Half-Life 2: Episode One, however.

Alternate Intro

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

Loading the map intro.bsp via the Developer Console will get you to a slightly different version of the game's intro. The difference between Chapter 1's intro and intro.bsp is that there is no title card at the beginning, missing textures around the Spectrometer meaning that the older textures for it was replaced during development and instead of the Citadel, the intro loads into the railway which was seen during E3 2004. The intro doesn't end as the map doesn't load properly. This suggests that it was originally going to have its own, separate map, rather than being a part of d1_trainstation. This was probably removed to avoid creating another loading screen between the intro and gameplay.

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.
