The genius of E4M1 and E5M1 is that these levels absolutely require strategy. The standard "shoot everyone in sight" tactic fails miserably in these two levels. You will have to improvise and take unusual routes. Prepare yourself, young heretic!

You'd better quicksave a lot, unless you really want to do 3-parters :P
