This is a demo of Cryptic Passage by Sunstorm Interactive released in 1997, Included in the demo is the first level of these expansion pack, This file came from archive.org and I do not take credit for the demo nor do I own the demo either.
Running this one is a bit tricky, You must have a FULL version of Blood to run this demo, Either use the GOG.Com version of Blood Fresh Supply or drag the file to the BloodGDX or NBlood Folder and place them in a addons folder.
