When I tried to download the mods that was provided at their website... the webpage was seized by FBI because of copyright violation.. So, The moderator should at least inform the people that the files at are seized by FBI... I don't think you can download these file.

Nice, this sounds kind of like a Serbian Paranoia on the Source engine! The level design is lacking a lot though, I'm not too sure what sort of environment those shots depict because the textures and props are quite random... SAJ forces sound awesome, can't wait to see them in-game!

A note for everyone btw, if you're interested in mods about Serbia, keep watching the mod list ;)
