Counter Strike Doom Legacy "Standalone" (2014) file

This mod was made back in 2014, as an expansion of Counter-Strike Doom 3, another mod by AlphaEnt. Due to some requests, and to celebrate my 10 years of Doom modding (also, 10 years of my 1st CSDoom mod), i've decided to reupload this CSDoom 3 expansion as a standalone mod. So, this is pretty much the same as the original expansion included in Counter-Strike Doom 3, but without the complete download and additional files.
