i Agree 100% on all of this cause i want all this as bad as any other person who has wanted this i mean the terrain idea is beyond thinking i mean just think how awesome forge would be awesome with pelican,phantoms,real structures,and a huge ass map that we can build any thing on, changing terrain add vehicles like the frigate Or the corvette and drop pods and we need a huge campaign like halo 2 just imagine halo 4 you playing it right now and all this cool stuff is in it you may be driving pelican to drop off troops but suddenly you get shot down but some but let me add something to take it to the next level but what if this all happen in theater mode where before you play the map you can make a cool short video for the beginning like i the one i just said then you could spawn by the crashed pelican. see there's so many ideas that halo fans have but we are limited to what we can think of 343 should add all of this stuff to make halo 4 the game of the century it would be so awesome to pull this off 343 i hope they read this comment.
