this is what i think. i think halo 3 should have offline bots, and a BETTER online system. more people capable online, like black hawk down. i also think that the environment should be destroyable. make the ground able to be blown, so you can make bunkers in the ground, and have a map editer, so you can make your own maps. make the maps bigger, different vehicles, you can edit your vehicles so you can change colors and add different features. also, you should add a character edit, so you can customize wat your suit is like (if your halo dude), and like sum 1 else said, you can strip from your costume if you are stuck, but it strips most of your defense until you can find another suit hanging up. if your the alien, i guess your screwed. also add different people variations. plus, add a feature that you can swim under water for a limited time. you also should add a stats ability, that applies to online, too. like, muscle, stamina, agility, no health, jumping, stealth, and movement speed. also add height, CUSTOMIZABLE ICONS, more than just 2 colors, and more weapons. make it to where you can gain access to the helicopter things, and you can parachute off of it, but it needs two people to fly it, and if anti-aircraft rockets hit it, then the people flying it can abandon, and the aircraft will just glide on until it is destroyed. a major stealth feature should be added, too.
also, add 3rd person view, if you wanna change it in options screen, or macro it to a button
i dont care if this game is postponned 4 these features, because it would just make it 10x better. and i stress, plz plz plz make online games to where you can make them like rainbow six 3, instaed of bungie hosting all of them. bungie has discouraged many from buying halo 2. plz take my features into consideration, and if you agree, any1, then copy and paste this post on different websites forums all over so we can get the point through. thank you
