The infamous Gluon gets the Black Mesa treatment in an impressive display of development at different stages of progress.  Will Black Mesa make a 2009 release?  It appears the mod could already be in the hands of Valve so a release around Christmas would be a great present for all fans to enjoy.

The Black Mesa Wiki has also been released.

Gluon development

The Gluon was a tough weapon to get right, and has gone through many iterations.
Shown here are most of them from beginning to end, except for the final version, 😉
Disclaimer: This is still a work in progress, not final.
