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

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.

@Mark Laidlaw

The canon of the Half-Life and Portal series has never been officially defined by Valve, and never will be.
Series writer Marc Laidlaw stated that the issue of canon is “something the fans came up with” and that they do not have an official stance on it. He remarked that they “do not get involved in issues of canonicity” and that “canon itself is non-canon”, letting the games stand on their own.
