Remember those hellish pentagrams which had the marine face (Doom 1/2) and the U.A.C. Logo in them, well the dope fish is also there. Just look very carefully in the center of the pentagram and he will be there, though it looks a bit different from the original dope fish. As always, ID software has put in a dopefish into almost every game it made (Quake, R.O.T.T., etc.) as a tribute to the well of wishes in Commander Keen.
