I'd love to see Halo 4 with the same, or at least similar, style as Halo 2 had. The multiplayer experience that Halo 2 offered was the best, and for me still beats all other Halo games. I love all the games, but I enjoyed the style of Halo 2 the most out of all the installments so far. No more armor abilities...it's too much toward the cod direction, and Halo is most definitely not Cod. Halo needs to stay with its own identity and not try to copy off of modern warfare and such like it. 343 needs to get back to Halo's roots and look at how Halo 2 was set up in my opinion.
