BloodNet Amiga

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!
