The D-Pad: A Game Changer
Halo has never exploited the D-Pad’s true potential. The correct type of function to map to the D-Pad’s Directionals is specific: Toggles. Things that do not immediately affect gameplay, like choosing the grenade type you have equipped, are good D-Pad functions. What other toggles could Halo employ to enrich gameplay?
We saw Chief fire a grenade from, what I perceive to be, a Magnum. This suggests that each weapon will have multiple firing modes. Since shooting a grenade from a Magnum cannot be accomplished by flipping a switch on the weapon, like changing from fully automatic to semi automatic, I propose that each weapon has an “Alternate Ammo”. The Magnum has Standard Ammo, bullets, and Alternate Ammo, grenades. One D-Pad Directional would be dedicated to switching your current weapon’s ammo from Standard Ammo to Alternate Ammo and back.
Halo 3 had Equipment that could be deployed into the environment. I believe Halo 4 will have Equipment as well. The difference between Halo 3 and Halo 4 Equipment, besides their functions, is the fact that Halo 4 will allow Chief to carry two Equipment items at one time. Similar to how the Ammo Toggle switches from Standard to Alternate Ammo, the Equipment toggle would switch from your Primary to Secondary Equipment and back.
We saw Chief using a Flashlight in the trailer. What does the Flashlight do? It augments Chiefs vision by illuminating dark areas. If we continue using this theme of vision modification we could also suggest that the VISR system, from ODST, be another toggleable vision modifier. The last vision modifier is the Laser Beam. The Laser Beam does not illuminate dark areas like the Flashlight but causes enemies in dark areas to glow when the Laser Beam contacts them. Pointing the Laser Beam at an enemy’s face will momentarily obscure their vision.
The vision toggle is the only toggle that causes an immediate effect (turn on Flashlight, turn on VISR, turn on Laser Beam). All other toggles are merely selectors that do nothing until being deployed with another button (grenades, gun, equipment).
To summarize:
D-Pad Toggles
Up - Grenade Toggle - Frag, Plasma, Gravity, Disc
Right - Ammo Toggle - Standard, Alternate
Down - Equipment Toggle - Primary, Secondary
Left - Vision Toggle - Normal, Flashlight, VISR, Laser Beam
