Wikipedia on Wolfenstein 3D development mentioned, that "... early concept of the game included some innovative stealth concepts—dragging dead bodies, swapping uniforms with fallen guards, silent attacks". It seems very interesting. Reason for not having it here was, that it "drastically slowed the game down and made the controls complicated".
Is it possible to obtain it, or see this version somewhere on the internet - videos or playable version would be best ... Thank You very much. :)
(I wonder if I should contact the developers about it, but perhaps this version is out - so I am asking there.)
