Half-Life: Alyx/Unused Models

This is a sub-page of Half-Life: Alyx.

To do: Still quite a few more models

Enemies

Headcrab

While the model itself is used in-game, There are animations and sequences that aren't.

This is early version of the Reviver headcrab type, Complete with mostly finished animations, as said in Half-Life: Alyx: The Last Hours, It's mentioned that the Reviver headcrab was supposed to be just a regular headcrab, albeit tinted blue, which would explain this being here.

Combine Soldiers

To do: Also has three placeholder alternate textures.

Referred internally as "combine_soldier_new_content" and "combine_recon" respectively. They are early models of the Combine soldiers, seen in the scrapped "Shooter" minigame from The Lab. They are rendered as red wireframes due to missing textures. An ArtStation post by Max Aristov shows the model fully textured.

"combine_soldier_new_content"	"combine_recon" Material Groups
	Default	Supression	Commander	Shotgun

Interface

inventory_template

An early version of the inventory selector. What's interesting is that there are 6 weapons in this early selector, with a crowbar as one of the options. In a developer interview with Valve, they explained that the crowbar was in the game at one point but was removed because players kept assuming they were Gordon Freeman. In the final game, the crowbar is not part of Alyx's arsenal but is used at the end of the game. It is still fully functional and is used in numerous mods.

vr_teleport

A model of an action prompt, used during the Vive era HLVR testing. It has two additional materials to symbolize crouching and hopping over a window.
Interestingly, the stick figure character in the first image is a separate texture, instead of being part of the ladder. Given that the ladder has a function called "ladder_indicator_align_sprite" perhaps there would be some type of animation attached to it.

Items

alyx_watch and grabbity_glove_model

Early versions of the gravity gloves. They are much more simplified compared to the final ones. The Gravity Gloves model was reused as an Easter egg in Russell's lab in an inaccessible room next to where you pick up the Russells.
It's interesting to note that claws share the same design and animations as those used in the gravity gun.

backpack_inventory

A placeholder blockout of a Backpack, Presumably for an inventory system akin to Saints and Sinners.

vr_alyxhealth

An early version of the health syringe.

Miscellaneous

Citizen_Battery_Turret

A placeholder model for a seemingly unused turret. The model's appearance resembles "brush models" found in GoldSource games, such as the first Half-Life.

holo_hacking_enemy

Judging by the name, it most likely would have been an enemy of some sort. It uses the same model as the leftover helicopter bomb.

The Lab and Dota 2 Models

Multiple models from The Lab's Robot Repair minigame and Dota 2 are left over. This makes sense, as both games were made using the Source 2 engine, just like Half-Life: Alyx.
