In the original Wolf3D four of the bosses are end game triggers.
These are Schabbs, Hitler, Giftmacher and Fettgesicht. When you kill them "Death Cams" follow.
To have more than one of these bosses in the same episode you need to disable the "Death Cams".
You can disable the "Death Cam" for one, more or all of these bosses.
Open Wl_act2.c
The following screenshots show how to disable the "Death Cam" for the Adolf Hitler boss.
Scroll down to the portion shown below.
This is what you need to do.
Comment out line 2855 (line 2807 in the unedited version).
Then add line 2856.
(The procedure is identical for the other bosses.)
In addition open Wl_state.c.
Scroll down to the portion shown below.
Comment out the lines 901 and 902.
(This procedure too is identical for the other bosses.)
Line 905 is added to make Hitler drop a gold key.
(More about this in the Edit bonus items and Edit enemies sections.)
