Cdda models some very long-range interactions, such as spotting enemies on open ground, hearing firearm reports and explosions and firing weapons with extremely long effective ranges (i.e. sniper rifles, 1,000ft+ effective range).
The current implementation of the game engine imposes a miniscule maximum interaction range of 60meters or so.
This project will endeavor to increase this effective range at which the player can interact with enemies and vice versa, while maintaining a reasonable level of challenge for the player.
