What if you kill the process that is running the Doom interface? Do your processes start running amok?
Hopefully, that isn't an option! I would assume, you the player are that process, so I guess a /kill at the console would do the trick.
I always wondered if he has the monsters juking or something. A smart web server monster camps out next to some pita process and right when you go to shoot that process, it jukes to the side, or your web process jumps in front, and blam, you spend the next two hours explaining to your boss what the hell happened. "No, it was that damn zombie's fault, I swear!"
That is an old program - real old. I remember seeing it and thinking 'how cool' like three or four years ago. I think he/she should change the UI though. Instead of heath and armor, it should be cpu and memory utiliaztion. The ammo part (left side) could be the number, or names if not that many, of people logged into the system. The ammo part (right side) could be du / df for all of the mounted filesystems, etc.
Hmm.... on second thought. Feel like doing a cross-platform Java version?
