[quote] But mastercheifs face didnt make since compared to cryosleep mastercheif should still be look like his like early thirties.[/quote] What does cryosleep Master Chief's face look like? This is the first time in the games where we get a small glimpse of his face. So there's nothing else to compare it to. Also he seen continues action from waking up until going back to Earth. So that would put a strain on him. And also The Librarian did something to him. Both of those things could have changed him.
