Halo Reach Controls are Going to Mess You Up
Have you ever intended to do a simple task, like switching grenade type, and instead accidentally vaulted yourself off a ledge with a jetpack? If you haven't, prepare to do it a few times while you get accustomed to the Halo Reach controls, which throw all of us for a loop by remapping some of our most used buttons.
As you can see from the diagram, the B button will no longer be your melee button, and will instead change grenades. Now, RB will melee. The reload button gets mapped over to 'X' since we no longer need to use the button to pick up equipment, which is replaced by Armor Abilities, now mapped to LB.
It seems a little counterintuitive having the "change grenades" button on the complete opposite side of the controller from "throw grenade", and using RB to melee is also going to take some getting used to. What are your thoughts?
