This game has unused areas. This game has unused code. This game has uncompiled source code. This game has unused graphics. This game has unused models. This game has unused items. This game has debugging material.

To do: Like Half-Life 2, there are tons of unused models that were either unused or leftovers from the original game, including content from City 17. Prototype Particles! A prototype build of Episode 2 dating to late 2006 was released in 2007 as a Source Particle Benchmark Demo, but the Demo is actually a complete prototype of Episode 2 minus the maps and assets, hence it qualifies for a page. A late June 2007 build of Half-Life 2: Episode Two was leaked in the source for the Postal III files, please create a prototype page about it.

Half-Life 2: Episode Two is the third part of the yet-unfinished adventure of Gordon Freeman where Eli Vance prepared for "Unforeseen Consequences".

Unused Textures

Unused Chapter VGUI Icons

Chapter 8. This is early Photoshop work on an image of an early version of ep2_outland_12a as seen from the HUD on the bottom-left corner and an extra Alyx, hence why only concept exists here.

ep2_intro.bsp was supposed to be loaded into the game, but it never appeared for nine entire years, then later got leaked on the Facepunch forums and quickly taken down by mad retail fans.

Both of them can be seen if you create a chapter0.cfg and/or chapter8.cfg in the ep2/cfg folder.

devtest.png

An overview of a removed map called devtest can be found. This map and other devtest maps were found in the NVidia Shield versions of Half-Life 2 and its episodes.

Early Magnusson

What appears to be an early rendition of Magnusson that can be found under "effects/magmonitor_idle" and "effects/magmonitor_talk".

Jalopy

A vehicle seen in the gameplay demos, but didn't make it to the retail and was replaced with the Muscle Car. The vehicle resembles the Scout Car from Half-Life 2. The texture and handling files for the Jalopy remain in the retail game's files. There are modifications online to restore this car, but the majority of them involves it replacing the Muscle Car.

Juvenile Advisor

The Barn Advisor originally started life as a Juvenile Advisor. The model seen to the right has been leaked a few times, but it doesn't exist in Episode Two by default. The texture does, however.

		ep2_train_trailer.mdl: This model can be seen in the trailer for Episode Two, where Alyx hangs from it and loses her grip. Its texture and VMT are located inside "materials/models/props_trainstation", if one were to copy-paste these two into a custom props_outland folder located in "materials/models", the textures show up correctly. Why the VMT points towards props_trainstation instead of _outland isn't clear.

Source Particle Benchmark

This is a demo of the new engine improvements, like shadows and particle showers. But people who have dissected the files have found some early content related to Episode Two within. The file level_voices_episode_02.txt shows there were some differences in speeches and that there were two cut rebel characters, Cyril and Fred, both named after science fiction writers Cyril M. Kornbluth and Frederik Pohl.

Combine Advisor Unused Particle Shield

The unused shield.

Found as "advisor_psychic_shield", this unused shield uses the Particle system shown in the Benchmark, but the file is found in the retail version.

Unused Combine Advisor Battle AI

This video shows unused Combine Advisor Battle AI, hinting that Gordon was originally to fight one in Episode Two. However, recreating this behavior requires a rebuild of the game engine to get it to work.

Unused Citadel Explosion Animations

There are various unused explosion animations for the Citadel that are never used in-game. It can be heard at the end of Episode One, but it can't be seen due to the Citadel being a simple skybox card, without animations. However it was seen in the unused map "ep2_intro.bsp", a modified of the final cutscene in HL2 EP1 only the citadel explosion animation seen.

Proto1 Weapon

There exists a sample weapon never compiled in the Source Engine 2007 branch of Episode Two. The only remnants of the weapon are source code referring to it. The compiled version of the weapon itself looks like a 357. Magnum, but in reality is a laser bolt weapon. Changing this string of the weapon script below will look exactly like an AR2, the only difference being it acting like a laser bolt rifle.
