Zac involuntarily takes Rob back in time 20 years to the year of video games and the release of the first Half-Life game. Shame the timing doesn't work out to be half our lives ago but ho-hum.
Take on the role of Gordon Freeman as he escapes the disastrous aftermath of an experiment gone wrong in the Black Mesa Research Facility.
As the Freeman works his way through Black Mesa, the danger grows. Bigger aliens, bigger guns and bigger vats of goo.
Trundle with us through even more ridiculous parts of Black Mesa, this time on a train. Note that the train does not make this section quick as you would expect.
Black Mesa makes an Amazon warehouse look like a tiny ant farm. Just how much residue is there to process? Zac and Rob investigate.
It’s finally time for everyone’s favourite headcrab! Surface Tension remains one of the more memorable parts of the Half Life campaign.
Zac and Rob guide Gordon through his efforts to escape the bombardment of Black Mesa. He might end up travelling a bit far.
Good thing there’s nothing weird and naked on the other side of that teleporter thing... oh.
