Make Halo Infinite’s custom games very “custom” for lack of a better term, like being able to edit the strengths of the equipment. Strong repulsor blast, long range grappleshots, shorter timers, etc. Another example would be melee speed.
Allow us to also use classic weapons like the covenant carbine, OG power weapon shotgun, or the spartan laser. I understand it can mess with the overall balance of the game but having it only available in custom games won’t affect the balance of normal multiplayer games.
Oh and let us customise how each weapon can play. For example; being able to edit melee speed, melee damage, and damage for each individual weapon, making the charge up speed for the plasma pistol faster to mimic a more classic feel.
