[quote][b]Posted by:[/b] Maimum FEAR I'm not entirely sure about stuff like the terminals and data pads, though as they are part of the game and story they can probably be considered canon. When I say Heroic is the canon difficulty I'm talking about damage, movement and weapon effect etc. rather than plot devices like the data pads. The data pads are probably all considered canon regardless of the difficulty, they will just be placed in different difficulties to make it more of a challenge to obtain them. I doubt any of them rank above others.[/quote] FYI those new novels coming out about the Forerunner-Flood war are based, at least partially, on the terminals in halo 3.
