After the resonance cascade triggered the quench protection of the accelerator, someone had to go down into the tunnel to fix it for the next beam injection. However there were unintended consequences to the experiment...
This is an amazing commission made for me by latex (https://www.furaffinity.net/user/latex ), showing my character in the LHC tunnel hunting for or rather getting hunted by headcrabs :)
And NO, they don't usually crawl around there ... :P
As requested by the artist, I scaled the private high-res picture to 1228 pixels.
