Superb Zomboss Radar, also called the Spotting Station, the Superb Radar, or simply Spotting, is an ability in Boss Mode for Plants vs. Zombies: Garden Warfare used on the zombie team. It costs 75 brains to deploy and self-destructs after 30 seconds of being deployed. It can reveal the location of all plants within its radius. Its plant counterpart is the Coconut Spotting Station. It can be destroyed by the plants and it takes 20 seconds to recharge.
Drop these Superb Radar Stations around the map. They will track the location of all nearby Plants and relay that info to the rest of your team.
