This is in fact the Retail Shareware version of the game, which was sold on CDs. The the files in this version are actually identical to the Retail Shareware (file list at cd.textfiles.com), except there are no cutscenes and no Windows installer.DOSGuy wrote:v0.99b includes an installer for the Total Entertainment Network, so I hope to find a version that contains only the game, if there was one.
The problem is that the Internet Shareware readme from other known versions explicitly forbid the distribution of Retail Shareware, as opposed to the Internet Shareware. You will probably want to remove that version from the site.
As for the existence of stand-alone downloads of Internet Shareware v0.99b and v0.99c (in addition to the respective patches), the change log at 3D Action Gamers' Archive seems to suggest that these versions indeed existed:
A download of v0.99c is also mentioned here. However, neither file seems to be available online currently.970326 : added Blood v0.99c shareware and upgrade patch (superseded v0.99b)
