I put online an index of ALL Mercenary-related fan works I made during the years, from 1997 to now. That includes something you may have never seen! The address is:

And the works included are:
* DukeDamocles
* All the stuff about the Mercenary 4 April fool
* Gamma System Explorer
* My attempt to develop Mercenary 4 in Dark Basic
* The Gamma system for Celestia
* My analysis of the screenshots of Damocles for PC
* TADPSID

Enjoy!
