im pretty sure lost of you remember in halo 3 where there were loads of objects and could be moved by you and turned into traps. i was a bit annoyed when playing reach and finding out that, there were only maybe 8 objects for moving, and there were just dice and balls which all shared the same counter, unlike in sandbox, where there were loads of moveable objects, which were blocks etc. in halo 4 i think it is much needed that, objects that are set to NORMAL physics actually stay like that even when they are set into place. that would be great for make makers trying to get a more destructive feel to there maps such as, a build flying across the map after being set off by a trap or something like that.
