Description: Flashpoints are weekly challenges with multiple steps. These will be unlocked over halfway through the main story, given by Cayde-6 at The Farm. He will ask you to go to Earth and set down some patrol beacons. From there, you'll need to do three patrol missions on any planet. These work just like they did in the first game, by interacting with any of the patrol beacons marked by a grey diamond on the map. These are usually very short tasks for killing enemies, collecting drops from enemies, etc. After those are complete, return to Cayde and he'll now ask that you complete public events. Once done there, return to Cayde to complete the Flashpoint and unlock the achievement.
