You can find 2 types of radar cheats.
Radars display player locations and loot on a webpage and not inside of your game. Once installed the weblink is visible to anyone in the same lobby.
1PC RADAR CHEATS:
These cheats are just like external cheats and will run on any system without any special setup.
2PC RADAR CHEATS:
These cheats require a main gaming PC and a 2nd PC or Laptop. You run the radar on your 2nd device and stream the cheats to your main gaming PC. These cheats are much more secure.
