Believe it or not - and I'd forgive you for not believing it, given the mod's torturous history - but this is reportedly a shot of notorious Half-Life remake Black Mesa. Like, its gold master disc. Meaning the thing is actually done.
Well, mostly done; as we told you last week, the mod won't quite contain the whole original game. But what's being included is on that disc, meaning a public release isn't far away.
The project has been selected as one of the first 10 games to be made available via Steam's Greenlight system.
