Team Fortress 2/Unused Models

There's a lot of unused models in here!

Flags
These unused flag models are in the same folder as the briefcase used for the flag in the final game. They're based off the flags in Team Fortress Classic.

Those faces, by the way, are those of Robin Walker and John Cook, the creators of TF.

Neutral Briefcase
This version of the Intel briefcase is fully functional, but is not used in any official levels. It was provided solely for designers of custom levels to use. It looks and behaves a lot like the team-coloured Intel briefcases, except that it's grey and both teams can pick it up. The Objective HUD supports One-Flag CTF using this item.

Payload Carts
Within the game files, there are 3 untextured models of unused Payload carts. Two of the models highly resemble a train, albeit scaled down a bit. The third model is based on a concept art image of a Payload cart.

Repair Node
An scrapped replacement for the Dispenser or Teleporter. Would have automatically healed nearby buildings for a while, before stopping to recharge. Cut because it made turtling too easy and slowed the game to a crawl; additionally, having it replace the dispenser or teleporters made Engineer less of a team player. Was fully modeled with no textures before being cut, but it can be seen in its completed form in the Engineer update preview video in the background.

Turrets
The original design of Team Fortress 2 appears to have had spawn room turrets; several different designs were created, including a large turret and a mini turret, but none of them made it into the final game.

Camera
A lightly rebranded Arriflex 435ES movie camera with a highly detailed model.

When asked about its planned purpose, Robin Walker said "I can’t quite remember. Might have been something for SFM. Or perhaps we built it when we were tinkering with a prototype of a spectator class who made movies of the match in realtime."

Scroll
Included as part of the Australian Christmas update. Its intended use is unknown, though it is in the DeGroot Keep materials folder.

Ticket Booth
Included as part of the Australian Christmas update. Its intended use is unknown, though it is in the DeGroot Keep materials folder.

Decapitation Models
Released along with the Eyelander, assumed to be scrapped models that would have been placed at the player's neck, when decapitated by the Eyelander. Only the Soldier's model was included in the VPK, but it is assumed all players would have had their own model, in a similar fashion to Max's Severed Head and Modest Pile of Hat.

Alternate Deathcam UI
Alternate version of the deathcam function. Would have depicted the F5'd deathcam picture landing on top of a pile of other pictures, all of which appear to have been taken from beta versions of the game.

Badlands Models
Within the "materials/models/props_badlands" folder are numerous textures with no associated model, such as textures for a helmet, a jetpack and a laser. While the associated models are not present in the VPK files, intrepid users have located the models and screenshots of them have appeared recently.

Source Filmmaker
All the unused content below was found in the Source Filmmaker internal beta, but weren't used in the actual game. (This really should be merged into an article for Source Filmmaker)

Old Fashioned Sentry Gun Model
In the Source Filmmaker internal beta there is an early game model of an old fashioned type of sentry gun with wheels and a brace at the end. The idea of moving sentries around most likely became irrelevant after the Engineer was given the ability to pick up a Sentry.

Pyroland Flower Spy
Appears to be a giant flower with a Spy's face. Despite the model's overall theme and style, it was not used in the Meet the Pyro video.

Comic Book Cover
The comic book cover you never get to see in the Meet the Medic video.

Strange Polaroid Texture
Judging by the image, this texture was likely an inside joke of some sort, or quite possibly meant to be part of one of the Meet the videos. This texture is one of the skins for the model of the polaroid picture used in the Meet the Spy video, among others. The other skins showcase images such as the Spy with the Scout's mother, a grinning Heavy, and the word "NO!" in red marker.

Interestingly, Source Filmmaker has a sound cache pathing referencing missing .wav files. A few of them are presumably about Spy getting hit by a car:

sound\vo\short_one\temp_dialog\02212012\scene_02_scout_why_car_hit_you.wav sound\vo\short_one\temp_dialog\02212012\scene_02_scout_why_car_hit_you_alt.wav sound\vo\short_one\temp_dialog\02212012\scene_02_spy_hit_by_car.wav

Robot Scout Blueprint
In the Engineer update teaser there is a blueprint where a robot hand can be seen. The full texture has been discovered in the internal beta of Source Filmmaker, and it appears to be the Robot Scout.
