Do you know the difference between Halo 3 and Halo 4? Do you know the difference between halo 3 helmet and halo 4 helmet? Someone has told me that, Ones made by Bungie the other is made by 343 Industries. One has Brutes the other has Prometheans. One has super powerful Covenant the other has weak covenant. One has duel wielding the other doesn't, One has disposable AA the other has infinite AA One has more vehicles and weapons the other has less. Do you agree with me?
About the helmet, Halo 4 Master Chief Helmet is more sophisticated than halo 3, look at the texture both of them. Look at the picture as follow you can find the difference. link: http://www.amazon.com/gp/product/B00B30484U/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00B30484U&linkCode=as2&tag=halo4link-20
