Crazy credits

End credits by Brett Patton illustrate each job by scenery and animated sequences from the game.

Final shot of the end credits, before the iD logo (which could count as post-credits scene due to titling absence), is a nearly exact replication of a famous title screen and box cover art of the original Doom (1993).
