Halo 5 will probably be amazing just as any other halo has been.
Like other people i to have a wish list and i think most of u will like it.
1. If they are keeping the ordnance drops in multi player a new weapon could be a revolving grenade launcher with 6 shots. - with a weapon this powerful or deceiving people will actually leave their teams alone to try and kill as many others with a gun like this causing them loose sight of an objective and allow the other team to have better chances to get the objective. at the same price the other team is getting demolished until the player runs out of ammo. This weapons projectiles should not bounce like the grenade launcher in reach they should explode on contact.
2. Being able to duel wield small and large weapons together. - For example sword and pistol, rocket launcher and pistol, rocket launcher and smg, Spartan laser and needler. You get the point. allows players to have a little more defense.
3. New vehicles for marines and covenant. Marine vehicles- similar to a BTR in our modern day armed forces.
gunships for both sides. heavily armed.
