Halo 4 as you may know, is an upcoming game in Q4 of this year. There has been much speculation on what this game will be about, will include, etc…
Here is what I can piece together through research.
Halo 4 will in fact include the Master chief (John-117))
Will also include Cortana who is nearing the end of her life span and may or may not have gone rampant.
At least some of halo 4 will take place on a mysterious forerunner shield planet which can be seen from halo 3’s legendary ending and the halo 4 teaser trailer.
Master chief will have a new armor, but it is unknown whether it will be the Mark VII or the upgraded Mark VI.
The game will be taken place in 2556. The same year halo 3 ended.
The game will return as a first person shooter, but will go more in depth with exploration, mystery, and discovery.
Halo 4 will be the first installment in the Reclaimer Trilogy.
Halo 4 will have forge mode.
Now here is some stuff that I have found but may or may not be proven true.
The forerunners, or Precursors, or the flood will be in the game.
The UNSC, elites, and/or the covenant may make a return in the game.
Halo 4 may be released on the xbox 360 AND the XBN (xbox next)
I also saw that somebody had said that halo 4 will be released on the ps3. I personally find that idea illogical. If Microsoft were to let ps3 use their biggest selling franchise then Microsoft would most likely see a huge decline in stocks. Because many people buy xbox’s to only play halo.
If you have any thoughts or further information. Feel free to state your mind.
