This is the version of the game that was initially released. When you install from the CDs, this is what you are getting.
No experience glitch. Does not crash randomly (see NASA2017 “run”) or at least not as often. Perhaps other differences yet known?
The current mainstay of the casual Bloodlines player. Maintained by Wesp5, or Werner Spahl.
A series of unofficial patches created by Tessera. It was meant to be a repair patch that only fixed bugs and problems with the shipped content, seen as a purist patch as opposed to the Unofficial Patch being a mod. The UP introduced two versions of their patch, a basic and a plus version, because this patch and it's team accused them of making large alterations to the game.
As of yet, this patch has not deeply been looked into for speedrunning purposes.
A mod designed by _xMAX_ that seems to make specific speed strats harder. Based on the Unofficial Patch.
