I'm familiar with the pits of course (I'm actually working in such an area now) I'm not familiar with that mod. I actually never saw any user made content until recently. It was dated 2006. It requires a modernized version such as vavoom or GZDoom. It uses features not available in the original executable. It felt like a real side mission. It was pretty cool. I think it would be cool to add it to my version in some way. There is unfortunately no voice acting for the new dialog. I am using the original dialog (most of which doesn't sound that bad considering its 8 bit).
