If you play Jessica, a woman who covers her face offers you a job. You have to go to an old tunnel system owned by the Oxygenetic company. Not in use for years, it's now inhabited by mutants, but she tells you that she found out the access terminal to Oxygenetic's intranet is still working. After you reach the terminal, you will enter cyberspace and look for information about Oxygenetic's oxygen production patents. You will find out that the system to produce oxygen has been invented by marine biologist Dr. Dmitry Oskanov, who is still working for Oxygenetic. After you leave cyberspace, you find yourself surrounded by company guards, who bring you into one of the company's prisons.
