The "Bloody moon of doom" is a small demo program, with which I tried the capabilities of OpenB3D in FreeBasic and which is like a springboard towards make similar 3D programs.
In this I used the resources of Doom, Blood and Rebel Moon Rising games and this program absolutely free.
I would like to thank the creators of FreeBasic development tool, the community of its forum, especially Angros47, who made OpenB3D.
Without them, this game of mine would not have been possible.
