Why are the elites being stupid? Master Chief is 7ft Elites are 8ft, you don't need to jump to get on the back of the Elites, in Halo: Reach the 'Spartan 3's' are shorter because they are human Spartans.
Also there are no brutes in Halo 4, I do not think of this game as a new 'game' I think it is a new campaign for Halo: Reach.
I can't wait to buy the game but I just don't like the fact there are no brutes, the elites can be in the game because of story line reasons like that Elites are in the Covenant but Brutes are a major part of the Halo 2 and Halo 3 campaigns.
Its a shame that Brutes could not be coded in the game engine because of laziness, forgetfulness or whatever reason. I cannot wait to buy the game, I know these things because the video leeks on YouTube of the campaign.
Best wishes 343.
