Specimen GG - Black Mesa Achievement

To get this acheivment you need to destory all 3 healing crystals at the same time. This can easily be done by placing C4 charges on each of the healing crystal locations and detonating them once they rise up.
Doing this will also make the Late for Work achievement much easier to obtain.

2:03 damn that looks really painful to the nihilanth

[@jasondo202]

so do u just bring the hat to the chamber and you get it?

[@TARINunit9]

Yes, the event flag is triggered as soon as you exit Interloper holding the Hat, so you thankfully don't have to babysit it during the Nihilanth fight. Note the achievement doesn't pop up until G-Man starts talking
