NEW: After almost 4 years, xbill 2.1 is available! Read more here.

More popular than Quake!1

Ever get the feeling that nothing is going right? You're a sysadmin, and someone's trying to destroy your computers. The little people running around the screen are trying to infect your computers with Wingdows [TM], a virus cleverly designed to resemble a popular operating system. Additionally, some computers are connected with network cables. When one computer on a network becomes infected, a spark will be sent down the cable, and will infect the computer on the other end when it reaches there.

That's the basic idea of the game. Pretty simple, but fun for a while, and definitely something to appreciate.

XBill was mostly written during the summer of 1994 by Brian Wellington and Matias Duarte, and has gone through several revisions since. The current version is 2.1. New ideas are appreciated, and if they sound interesting enough, may be implemented. Especially if those new ideas include graphics.

Here's a page describing some ideas for future versions.

Play the Java applet version, in its very unfinished state. It's not too much fun yet, but at least it runs. This is based on 2.0, and may be updated at some point. For some reason, it doesn't work too well with appletviewer, but that's not too important.

Anonymous cvs access should also be available sometime soon.
