So, its a dark, scary map. And you are to move to a location/do something, but you are constantly hunted by gigantic sentinels. They will search for the player with searchlights. Imagine running from cover to cover with searchlights all around you, gigantic robotic things flying in the air, searching for you.
I would want a dark, scary mission were you’re hunted, searchlights everywhere. This is more like a mission setting idea than a mission idea, either way this is what i would want on a mission.
