If you're the kind of person who likes to see how the sausage is made - and by sausage I mean stellar Half-Life remake Black Mesa - then there's a bit of a treat in store. Developer Crowbar Collective has just launched the Xen Museum, gathering a host of playable levels and other assorted material from all across Black Mesa's development.
More specifically, Xen Museum is (unsurprisingly) focussed on the Xen portion of Black Mesa, which saw Crowbar Collective designing a whole series of new stages to replace the lacklustre - and oft-criticised - alien planet sequence that closes out Valve's original Half-Life.
Crowbar Collective spent five years completing Black Mesa's version of Xen, generating a mountain of concept art, plans, and work-in-progress levels along the way. Some of that is showcased in Xen Museum, an official mod that feature a total of 56 playable stages.
