I bought mine instantly so I only found this out from my brother. Most of Freedoom (and any other free wads you might load ) is behind a paywall. Slight issue with that as the extras like 3d monsters and blood better lighting and hi res ( basicly the app ) are what we are paying for ( no issues with that like I said I bought and is happeh with ). I reckon its worth the price but peeps should be aware of these things.
