seriously gordon freeman i knew the criteria for being a cyborg was becoming more and more lax but i don't think wearing something makes you a cyborg the hev may provide him with morphine and oxygen but thats really all thats confirmed about it unless its revealed that he has special implants or something to link him to the suit i don't he and the suit could be considered one and the same which is the definition of cyborg it doesn't even fit the relaxed have machines attached to you requirements so can we really consider him a cyborg
