You can create a mod that removes the fog of war. However, you may want to try increasing sight instead so that true sight still works (i.e. squads can still hide behind bushes and buildings like in COH2 and COH3). Recommend adding a match option to your mod/mode so that the host can select what they want (e.g. default fog of war, no fog of war, +20% squad sight, +40% squad sight, +60% squad sight, etc.).

Note that it feels a bit weird to be able to see something but not be able to shoot it since weapon range is close to or greater than sight range in standard game play. If you find this, consider increasing weapon range to compensate. However, the risk with weapon range being much greater than half the screen width is that you are shooting (or being shot by) squads that are off screen. It's a fun experiment but does reveal that the default sight, range, camera, and fog of war settings are pretty darn good.

It would be easiest to implement through script (i.e. a game mode). A tuning pack would likely involve a lot more work, would be fixed (i.e. not customizable), and would require updating when Relic adds new units in future expansions.

Thank you for the reply. You make some good points.
