If your Science skill was too low, or if you just enjoyed the LSAT problem of trying to figure out how to brute force hack your way into a terminal in Fallout 3 then this flash game is for you. And look, no need to back out of the terminal before making your final attempt!
Complete with authentic keyboard-clacking and power-switch whoomphing, from mitchellthompson.net is this flash timewaster based on the good ol Robco Industries security protocol. I haven't gone to GameFAQs or my strat guide (yes, I bought one) to see if it's using real passwords or not—I don't think it is. I can't even tell if it has a correct answer or just one chosen at random. Anyway, here you go, drive yourself nuts.
