Gordon DID accept the offer you tards, its been said already by the dev's...the little section of story we do have... says you accepted his offer, regardless of your fate in Half-life 1. Know your stuff before you talk.
G-man has to be alien... notice you could never kill him.. nothing would ever attack him... he sounds like he has a problem with english... gotta be alien.
Gabe said they were experimenting with how many weapons you can hold, he also said he liked being able to carry around an entire armory in your pocket..so perhaps it could turn out like HL 1...just gotta wait and see.
