Half-Life (PlayStation 2)

Prototype Info Prerelease Info Bugs Half-Life: DecayUnused content found in the co-op campaign included with this PlayStation 2 port.

Unused Graphics#

Save Icon#

Texture	Save Icon

The lambda save icon texture has a ring around it that isn't used by the model.

Unused Models#

5ton#

A model-based version of the military trucks seen throughout the game. In-game they retain their original brush-based appearance. This truck's windows use a separate model. The model also has some animations: drive, drive_left, drive_right, tires_left and tires_right. Two submodels exist: one with opaque windows and another that is destroyed.

5ton_clear#

A model for the aforementioned truck's windows. Judging from the name, this window model is meant to be transparent.

bradley#

A model-based version of the M2 Bradleys seen in "Surface Tension" and "Forget about Freeman!". Just like the truck, they retain their original brush-based appearance in-game. The model also has a somewhat unfinished interior. A destroyed submodel also exists.

chumtoad#

The Chumtoad that seems to be directly ported from the PC version instead of getting the HD treatment.

Debug Console#

To do: Confirm if launching the ELF with the -console, -toconsole, or -dev arguments also enables it. If -dev is used, it'll also toggle sv_cheats and developer.

A debug console can be activated after either applying one of the codes below, or adding console "1" to system.cfg in the save data, and pressing ~ with an attached USB keyboard. The same European code applies to all five of the known regional releases.

PS2 Port Specific Console Commands & CVars#

To do: There are more commands and CVars, Look further into this.

Commands#

goto <x> <y> <z>

Teleports you to the specified coordinates.

fly

Supposed to make you fly, but doesn't seem to do anything.

impulse 222

An "impulse" command that gives the player infinite ammo, likely used for the corresponding unlockable cheat code.

Removed Video Display Mode#

Watch on YouTubeWithin guidef.txt, which contains the sources for the main menu GUI, is the option for a fully functional toggle between PAL/NTSC display modes that is completely commented out. When this is restored and activated, it toggles the game's refresh rate and internal vertical resolution between appropriate PAL and NTSC values.

Unused Sounds#

Alien Mode#

There are twelve variations of the "gibberish" that replaces the regular dialogue when playing in Alien Mode, however, only three of these variations are used.

Voice Outtakes#

To do: Do the outtakes belong in the Decay subpage?

Watch on YouTubeSince the Half-Life voice cast had to be brought back in to record new lines for Decay, the developers decided to have a bit of fun. According to Randy Pitchford, a special map was made for these, but it doesn't seem to be in the released game data.

Interestingly, these aren't just voice samples - there is a modified scientist model (outtakes_scientist.mdl) that contains a couple of additional animations relating to the name tag and Headcrab lines, and Dr. Keller has a lengthy "surprise" animation to go along with his little Dr. Strangelove tribute.

Campaign and Decay Model Differences#

The main story campaign and Decay use a different set of models from each other. While this mostly results in the model textures in Decay having a lower resolution, there are some models that have some unique differences between the two versions.

Agrunt#

The Alien Grunt's texture in Decay has less saturated colors, and its skin is less shiny.

Barney#

The security guard's leg holder strap in Decay is modeled into his leg. The security guard's arms, hands, and legs are also thicker.

Zombie#

The zombie's labcoat in Decay is much bloodier than the main campaign's, and their shoes aren't shiny.

Regional Differences#

To do: Europe has some of its levels revisioned with bug fixes.

This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this.

Europe#

These changes are shared across all five of the known regional releases (Germany, Spain, France, United Kingdom, Italy).

Anomalous Materials#

A few scientists can no longer be forcibly pushed by the player to open doors or skip sections of the chapter. All 3 scientists in the control room and both scientists right before the test chamber are affected.

Intensity dialog#

The aforementioned secret dialog in the mission Intensity is absent, and can't be triggered.
While the sound entry in sentences.txt was removed and the map modified, the line was still translated into other languages.

Germany#

German releases of Half-Life on PlayStation 2 feature mostly identical censorship to the PC counterpart.

Robot Grunt#

Like in the original release, the Human Grunts have been replaced by robots. The model was remade to keep with the game's upgraded visuals. They have the rank insignia of a corporal on their left arm and a white star surrounded by a circle on their chest.

Of interest is that Decay specific lines are simply spoken in a normal human voice instead of having a robotic filter, and they are still referred to as being "soldiers" by other characters.

Violence#

Low violence mode is enabled, removing all forms of gibs and blood, and characters fade away whenever they are gibbed. However, Barnacles spew normal human gibs, as the mechanical gibs replacement wasn't ported over.

Like in the original, when a scientist or security guard is killed, they will sit down with their legs crossed and shake their head from side to side in disappointment. Those put into the "sit down" state are still considered solid for a while, and can even be gibbed.

Anomalous Materials#

The sitting scientist with a headcrab on his head was completely removed from the map c1a1a.

Oddities#

Alien Mode#

• The Alien Slave "weapon" used for the Alien Mode reuses the Crowbar's world model, player model (p_ model) and HUD icon. These normally go unseen as this "weapon" is given to the player as soon as the game starts in Alien Mode.
  • It also has unused cooldowns for its melee attack depending on the animation. In the final game, the attack cooldown is determined by a preset value.
• For some reason, the health station's canister does not drain while in Alien Mode.

0xDEADBEEF#

Watch on YouTubeA code oddity like no other. Four console commands seemingly exclusive to this port, those being memmodels, memsound, memhunk and memall, only output 2 different outputs, one of them being 0xDEADBEEF. At one point, these commands were seemingly working before having their functions dummied out for whatever reason. These commands can be easily patched to have their functionality restored.
