PsDooM

psDooM is a varient of Doom, which interacts with ps, and represents processes as enemy bots. This gives the sysadmin the ability to literally kill rogue processes. However, the bot AIs are currently still fully functional. Orginally, this meant that maps for psDooM have to be carefully planned, lest the processes kill each other (including psDooM itself!). However, in newer versions, only the human player can kill or renice processes, by default.

Wounding a process bot [[renice]s it +5, killing it sends it a kill -9 signal. (Terminating it.)

(The psDooM process would make for a nice end-game boss...)
