Tips:
John Romero's Head On a Stick:

On both - Plutonia and TNT's 30th levels, find the huge goat head that shoots out 
the enemies. Now type in the no clipping mode cheat (idclip) and go into the the 
head. Inside is John Romero's head on a stick. Now shoot him in the head and he 
makes a funny painful face.
