I mean, it shows his face in this game, and he looks like an ordinary human being. in Tcon half his face was concealed in darkness giving it a mystery to his identity. I kinda imagined adams having dark, scary alien eyes and being taller. in this he looks like an office worker.
that was him. if you notice in the background you hear something along the lines of ford saying "ADAMS!!! IM GOING TO GET YOU!" and "haha! good luck getting over here! muahahaha!" before he leaves through his conduit
hmmm well i hope its not one of those "im gonna hide behind this giant vault door while these sentry guns shoot at you" type of fights. I want to actually fight adams. Like make him shapeshift into his true form (some freakish annunaki creature) and have him attack you wesker style.
