When I'd finished the excellent Half-Life remake mod Black Mesa
I was a bit discombobulated. I looked at the clock and realised that my allotted ten hour slot for playing it had come up short. I was a full 53 minutes early. What was going on? The only explanation was there was a time slip while I was hopping around being Gordon. I put it down to a rogue CERN test and moved on with my life. But now I've been made aware of Surface Tension Uncut
, a mod that restores the Surface Tension section from the original Half-Life to its full glory in Black Mesa.
