Just a demo only has two megawads currently. Wait a few days for a new update I'm trying to stop myself from pumping out these things, 20 megawads is too many megawads in a single pack of wads. Install instructions should be in the zip file. (I have to warn you I'm not really good at making instructions for things like mods)
