I never played 3D WS, but I did play the WS for DOS 6.0
dude... that was the second incarnation of wolf3d. ;-)
The first incarnation was in 2 colors (monocrome) if I remember right, and it sucked so bad that nobody player that unless they were unbelievably bored. (nintendo was better at that point)
As far as the rocket launcher... I am not sure... see... I remember there was a flamethrower, but that was for the registered version.
I only had the sharewared episode 1.
Also... in the full reg version you go back in after you escape in the first episode... and then you fight some doctor guy who throws hypodermics at you and soome other heavy weapons boss. I had the full version for the mac, but my mac was ancient and it ran like mollsasses... so anything I did in it was cheat mode or I wouldn't be able to live more than half a second.
btw.... never did cheat in the first one on the imbclone :-)
Ohh... the treasure chest sound will vary a little bit depending on what sound card or PC speaker you had. I forget what mine had, but it sounded pretty goofy. I actually heard 2 of the 3 types of counds (I think there were 3) because I had 2 computers who were of different cards... the adlib and the pcspeaker. :-p
