to all idiots saying hey I got more then what's needed for the badge, the game counts downwards! You start with all points (did all levels with 99/999 commands) and you are to improve that and get a score below 3000 which is better.
Great game, took me very long, a hint, if you are stuck and do not know what to do, play something else and come back another time when you are fresh again.
people should know their classics, DOOM is a very old game (well old for pc games), ofcourse the graphics are sucky, back in the day it was the best they could do.
