Half-Life: Blue Shift - Blue Shift Unlocked

This pack of files is intended to allow owners of Half-Life and Blue Shift to convert their Blue Shift installation into a Half-Life mod. This mod should be compatible with both WON and Steam installations of Half-Life.

Blue Shift: Unlocked


By the Half-Life Improvement Team



This pack of files is intended to allow owners of Half-Life and

Blue Shift to convert their Blue Shift installation into a Half-Life

mod. This mod should be compatible with both retail (WON/CD installed)

and Steam installations of Half-Life.



Due to the fact that Blue Shift was originally designed to be included

in the Dreamcast version of Half-Life, which was later cancelled, the

BSP map file format was a little different than the standard PC format.

Gearbox never converted it back to the PC format, instead opting to use

their modified version of the Half-Life engine when they released it

for the PC. This meant that the Blue Shift maps were not compatible

with the normal Half-Life engine.

Valve's official Steam port of Blue Shift is riddled with issues of its

own. On the surface, key parts of the interface have been poorly ported

or not ported at all. Under the hood, the maps remain unconverted, and

a lot of redundant Half-Life content is also present in the GCF, adding

at least 100 to 150 MB of useless data. In addition, this port doesn't

recognize custom content (models, etc.). In short, this port of Blue

Shift falls far short of Valve's usual high standard of quality.



This conversion pack requires that you have Blue Shift installed. The

Blue Shift game content (maps, models, sprites, etc.) is not included

in this package. This is done for legal and practical reasons. It is

meant to give owners of Blue Shift the option of playing the game under

a Half-Life installation, not to distribute the game to people who have

not purchased it.

v1.1 - October 25, 2005

- project name changed to "Blue Shift: Unlocked"

- new Steam background image by RavenGT (see credits)

- mod directory renamed to "bshift_unlocked", since Steam now prevents

any mod with the directory name of "bshift" from appearing in the

games list

not working on some systems

- optimised the game code, reduced the filesize of the game DLL

- setup changes:

- an automated installer version is now available, in addition to

the ZIP file version

- please note that this is a "clean" installer: it will not add any

trash to your system (desktop/Start menu icons, registry entries,

etc.)- it only extracts and copies files, nothing else

- user can now choose to copy content from the retail (WON/CD

version), or the official Steam version

- now checks if the patched map "ba_yard5" is already present before

extracting it from the PAK file (WON/CD version)

- fixed a game crash caused by missing parts of the human grunt model,

if the user didn't have the High Definition content installed

- changes to the standard Half-Life code:

- added all Blue Shift entities:

- env_warpball

- trigger_playerfreeze

- fixed the crowbar hitting dead bodies on every frame of animation
