In short, I'm not sure to be welcomed by Ostap here, that's why I decided not to post any maps anymore, though, if people ask for it, I may push my newest levels on this site.

This is a pack of 2 levels, that contains new enemies which are compatible with the vanilla game (no need to install mod), there's a readme file in order on how to install but basically:
- Open Insomnium.zip
- Extract its content (Bin, Classes & Insomnium.gro) in your main Serious Sam directory
- Play the game and the maps
