so hello, i’m new to the forums and i wanted to thank the devs for the great work and all that, but this is a question that really is bothering me…
so you get an achievement when you get killed by a headcrab, can’t remember the name but the description says: “get possessed by a headcrab” but after i’m dead nothing happens… so my question is :can you really get possessed by an headcrab?
No it’s a joke. You just have to die by a headcrab to get an achievement. It’s a play on the game idea that when other scientists die, they get possessed and turn into Zombies. When you die, you just reload.
i note forumguy’s sarcasm in his message 
It’s foreshadowing for the planned spin-off: Black Mesa: The Headcrab Chronicles. Valve and Gearbox have already covered the story from the perspective of Gordon Freeman, Adrian Shepard, and Barney Calhoun. That leaves a huge opening for the Black Mesa team to tell the story from the unique perspective of those lovable scamps we know as headcrabs.
You are Hedd Krabb, a middle class headcrab whose comfortable world is rocked when a resonance cascade teleports him to another dimension. You’ll laugh, you’ll cry, you’ll attach yourself to a scientist’s neck and shamble around at 1 mph while moaning. Black Mesa: The Headcrab Chronicles. Coming to your PC September 2024
