This is standalone? Why not just compress it and make it smaller and save space by making it work in sourcemods instead?

All 3 parts downloaded ok. Unpacking was a bit troublesome due to few errors, but after I repaired all archives, it unpacked nicely. Installed and played. AI indeed was not very good, but overall playable. Short, even for a demo.

AI will be good, only that one is worse than others. You will see when I finish the mod. And, that was Secret Of The Sickness 2. Sickness 1 is finished on january. Look on downloads page. :)

This mod is terrible. I tried playing it but I couldn't. The replaced sounds are terrible and the AI is worse than the original.

Wow, that explains why there's no votes. No offense, but this is the worst way I've ever seen to download a mod from MODDB.
