formerly NetRunner BBS Door Game

MatrixRunner is a free online multiplayer game based on the genre of Cyberpunk, such as William Gibson's book Neuromancer. The object is to break into computers and steal as much money as you can. To do this, you have a cyberdeck, and various programs. But the systems you are attempting to break into also have programs (called ICE: Intrusion Counter Electronics) that will try to prevent you from breaking in. These programs can do anything from alerting a computer operator who will drop carrier on you, corrupting your programs, frying your deck, or even trying to kill you by sending a voltage spike down the line. Along the way you will have deal with viruses, corrupted programs, etc.

I originally wrote this game back in 1991-94 to run on Bulletin Board Systems (BBS). I was recently contacted by some people who were interested in the game, so I decided to port it to the web as a PERL CGI.
I was surprised to hear that people thought I had vanished in 1992. From 1992-94, I was very active on several Seattle area BBSs including Cyberspace BBS, Hello Central, and Chat Chat Chat. On the last two, my nym was Shy Flirt. Actually, I was working on NetRunner up to 1994, when I moved from Seattle to Rochester NY, where there were no BBSs like the ones I was used to. Then the World Wide Web happened, and I got involved on the internet putting up my first webpage in late 1994, or early 1995. I released a shareware program called Gedpage for creating genealogy web pages. In 1998, I got back into karate, and soon I had a web site called Everything Isshinryu, which I later moved to its own domain. I have also put up several other sites, including, and a site for my wife (who I met on Chat Chat Chat BBS) called If you do a google search on my name "Rob Jacob" 5 of the first 10 pages are mine (I am not the MIT computer science guy). So I am surprised that people couldn't find me.
