An awesome conversion of the Renegade Single Player and Custom maps to an Online Cooperative game mode in a First Person Shooter environment.
The Ion Cannon Beacon can be used to end a map, win it.
You place one on the Pedestal then.
The Beacon Buy Icon only highlights after completing all objectives on the map, then you can buy a beacon and end the mission. (some maps you will be granted or dropped in a beacon powerup instead)
