Half-Life: Dreamcast is a PC port of the unreleased Sega Dreamcast console version of Half-Life developed by Gearbox Software originally slated for release in late 2000. The Dreamcast version possesses many unique differences compared to the original PC game and Gearbox's later PlayStation 2 port, including modified levels, exclusive NPC models and props not seen anywhere else, adjusted difficulty, and a host of sly Dreamcast references hidden throughout, making it a worthwhile curiosity that any true Half-Life fan would want check out. This PC port allows the game to run as a Half-Life mod on Steam.

Prepare to run, think, shoot, and live once again in the Dreamcast experience you've never experienced!

Mod Features:
• Different Maps - The map alterations range from minor geometry fixes and lighting adjustments to entirely revamped areas. Several locations have been redesigned with performance and gameplay in mind while entirely new rooms have been added in some places to introduce another obstacle or puzzle to overcome. One entire level was even cut! Can you determine the missing map?
• Different Models - The Dreamcast version is host to a number of exclusive models not seen in any other version of Half-Life, including the High Definition pack and the PlayStation 2 port. Can you find the hidden VMU and Half-Life Dreamcast disc?
• Revamped Menu - Included is a new splash screen, menu background, menu color scheme, and menu sounds to closely emulate the Dreamcast's fancy interface.
• High quality soundtrack - Emulates the CD quality music used in the console version, overriding the default 48kbps mp3s on Steam.
• Tweaked Difficulty - To accommodate the difficulty of playing with a controller, Gearbox suitably rebalanced the monster spawns as well as enemy health and damage values.
• Password Notifications - Although the password system itself cannot be ported, all password messages that appear in normal gameplay have been brought over.
• The Little Differences - Too small to be noted in a bullet point, but true Half-life fans should be able to spot these in a heartbeat when they see (or hear!) them.

In light of the new Linux, Mac, and SteamPipe additions made to Half-Life on Steam, a required update was made necessary for the mod. Hence, version 1.1 of Half-Life: Dreamcast is now available to add full compatibility with the recent Steam changes. Due to the nature of this update, a single patch is not possible. Be sure to delete the previous version of the mod before installing 1.1!

Head to the download section now or simply click the link below:

Half-Life: Dreamcast v1.1

Be sure you have Half-Life on Steam installed!

If you encounter issues such as scripted sequences not working, chances are your saved games from the base Half-Life game are conflicting with the HL: DC mod. This can occur even if you don't load these saved games. To address this problem, go to your Half-Life save game directory ( C:\Program Files (x86)\Steam\steamapps\ [SteamName]\half-life\valve\SAVE ) and either delete all files you find there or temporarily move them to a different folder. You may need to disable Steam Cloud synchronization for Half-Life to prevent Steam from automatically redownloading the saved games.

Some glitches you guys should fix:

1: In on a rail some of the little walls on the sides of the tracks are missing so you can see off the map were you shouldn't be able to see.

2:During the tentacle level when your going to turn that one generator thingy that that one guy is hiding on before you get there you should meet a scientist by some dials who will tell you they sent a scientist to go do it but he never came back. But for some reason the scientist who is supposed to say that does not say anything to you and seems to be missing that dialog.

3:At the beginning of on a rail when the security guard tells you to go launch the rocket he should walk over to the switch and use it to open the little gate. For some reason he wont open the gate after his speech.

I am at the lambda complex so far so after i beat the game ill let you know if i find any more glitches.

Actually as far as I remember the guard you speak of in #3 only does that in Half-Life: Source and not in the original.

Sometimes he actually pulls the switch in the original HL as well. Probably due to me pushing him around and activating the scripted sequence for him.

I finally found the cut level.


In the beginning of the chapter Interloper, there was a little level in which you had to launch yourself into the air and land on a portal floating. Not anymore.
Personally, I appeal this change. That map was a bitch to get past to.

This is perfect! When I bought Half-Life 1, the sound never worked on it. If this is basically a revamped Half-Life 1 campaign, then I don't need to spend so much time trying to fix it.

I think I remember seeing something about this in a video game magazine back in the late 90s or early 2000s, but it's all vague.

well it says the first verison so he may work on the maps one day. But I don't think the maps changed in the dream cast well to say it could be only the map textures that changed
