I dont know but found some hint about "DEATHWARE/Mindscape/1997":
DEATHWARE PC GAME
Systeemvereisten : DOS5.0 or higher, WIN95 – Pentium 60.
The ultimate collection of killer shareware (Full versions of Duke Nukem & Duke Nukem II included. Shareware versions of : Quake, WARWIND, Heretic, Necrodome, Megarace2, Wolfenstein 3D, Descent, terminal Velocity, Ultimate Doom.
If all those mentioned games are of MINDSCAPE origin its quite possible that DEATHWARE is a collector edition or something...does it fit with the release of the games?!

Bloodnet
You play as Ransom Stark, a computer hacker, scrounger or mercenary (depending on how the player answers the opening questions when they start a new game) who finds himself caught up in a sinister affair involving an evil global megacorporation, TransTechnicals, Manhattan, a fight for Cyberspace and vampires!
Ransom Stark became stricken with Hopkins-Brie Ontology Syndrome whilst working at TransTechnicals, due to his forced extended exposure to Cyberspace while he worked there. As soon as he was diagnosed he was dismissed from TransTech and found himself homeless and hopeless. Thankfully an ingenious woman, with a personal vendetta against TransTech, named Deirdre Tackett saved his life by inserting a prototype brain implant of her own design and this restoring his grip on reality.
Over the following year Ransom became known as a reliable freelance until one day he got a job worth much more than he bargained for! His employers turned out to be vampires and as part of his 'payment', Ransom was turned into a follower of the evil head-vampire, Abraham Van Helsing -- except his brain implant kicked in allowing him to keep temporary control of his humanity.
Now Ransom must put a stop to Van Helsing's plans to take over Manhattan and control Cyberspace and hopefully save himself from being a vampire before its too late!
BloodNet is an adventure game with RPG elements
