Tiberium Origins lets you play all four sides from Tiberian Dawn and Red Alert in one game, plus two more. It features Tiberium as a third resource, more valuable than ore and gems, bringing a new gameplay element to command and conquer. All four sides have their original units and structures implemented, plus a few new ones.
Contains both Tiberian Dawn and Red Alert ingame music. Download and extract to your OpenRA folder.
The file contains rascores.mix and cscores.mix - the music from the original games. Therese files need to be copied to \OpenRA\Mods\to\packages. I've packed both files with complete directory structure, so all you need to do is extract the included archive into your OpenRA folder, overwriting when prompted.
The music should be visible in Extras - > Music and ingame in the setting menu - music.
If the music isn't visible, or the game crashes refrencing either cscores.mix or rascores.mix, extrect the file to desktop, find the two files and copy them manually to your .\Openra\mods\to\packages folder.
