Doom II has text screens before Levels 7, 12, 21, and at the very end(See below), as well as before both secret levels (which are played after Level 15). Both episodes of Final Doom operate exactly the same way, as they were originally alternate Doom II PWADs. The same music is used for all of these text screens from The Plutonia Experiment, with the exception of those of TNT: Evilution, which uses an original, four-second track for the screens.
