Sorry if what I writed makes no sense to you (this is my first topic of this type “Discussions”) and I’m not perfect on English too… 
And if Halo 4 is a evolution of the previous Halos?
I see topics talking about “Halo is copying COD with perks, killcams, etc” and they may be right or WRONG!
I don’t think that…
What if the costumizable loudouts are just an evolution of the loudout system in Halo Reach.(allowing costumizable loudouts in multiplayer)
What if ordenance drops are just an evolution of Weapon drop from Reach’s firefight (taked even further to multiplayer)
What if the tactical packages and support upgrades are just an evolution of Reach Armor Abilities or in other words… more feautures with the same objective has Armor Abilities (Giving more support and ways to the players)
What if killcams “don’t know the name of this system” are just an evolution of the previous Halo’s theathre mode (taked to multiplayer, letting us know about the situation right in the moment)
yes they may sound and have the same objective has COD perks, killcams, loudouts etc…
But this is 343’s Halo, and maybe they add this feautures has an evolution of what previous Halo’s already add and not copying COD.
These are very distinctive games, both good at their own way.
So its possible that we can call Halo 4 new feautures has an “evolution” and not CODish things?
I don’t wanna start a game war, just hate to see people complaining about a game that I believe that its gonna bring back Halo 3’s or 1 huge sucess level has unique games.
And again, this might had no sense to you but anyway, just wanted to give it a try at sharing my thoughts…

But I completely agree with you. 343i knows what theyre up against and they know some people will say “Oh it’s a copy of COD”. But they’re bringing in more areas to where you can customize your spartan to fit your own personality instead of just giving you a spartan and being told to go kill people.
