Well, looks like Gordon does have an helmet afterall

I found this on r/HalfLife/

And here’s where it’s taken from: https://scifi.stackexchange.com/questions/35781/how-did-gordon-freeman-survive-the-entire-storyline-without-a-helmet/35784

I know that the source is a bit wonky, but I do believe that he’s actually Chuck Jones.

Hopefully it will finally settle the eternal question of helmet vs no helmet :stuck_out_tongue:

Yeah, it is mentioned by a scientist in the lockerroom that the earlier versions of the Hazzardous Environment Suit lacked an optional helmet. When Gordon came along, the individual who was developing the suit made the helmet optional.

Yeah but that was in Black Mesa, we never had a “canon” answer

Canon does not exist because there is no such thing.
