Dooming The Bar is a project centered on bringing the Half-Life 2 beta's City 17 into Doom, composed of a fully playable 8-map journey from the Industrial sector through to Kleiner's lab as per 2001 and 2002 concepts, plus two bonus maps.
You'll see famous landmarks like the Stenographer's Chasm, Terminal Plaza (with pendulum script!), Consulcast, Manhack Arcade (both versions!) and more on your travels.
