  1. Go to where you can see the lava, a good place is just before the exit. Turn towards the northeast, and you can spot a switch from afar. Shoot it to get a secret message "The dopefish is watching you" to trigger the secret. (linedef 5959 via thing 338, ZDoom's "secret trigger" actor) A soulsphere will also spawn.
