This achievement will be awarded for collecting all 350 crystal shards.
I've created an interactive map including all 350 of them.
http://swissgameguides.com/agents-of-mayhem/maps/worldI've also started adding screenshots (still WIP) for each shard that will show you the location and how to reach it. It should also help you to check on whether you've collected it or not.
Notes:- Crystal shards are the small red glowing spikes that can be found all over the city.
- Some shards are quite well hidden in bushes and holograms or in some offices inside the taller buildings of the city.
- Personally, I've used Fortune to collect all shards - so she can definitely reach all shards with her jump/dash ability.
- Collecting all shards in one go should take you ~3-5 hours.
- Some shards require you to use the purple-white looking platforms that can be found near the rooftops of the taller buildings. Hack the nearby stations (use scan ability to find them) to activate the platforms.
- Two shards require you to ride a specific yellow bot/airship in order to reach it.
- Your progress will be saved right after collecting a shard.
- For additional help, check requisitions on the ark and purchase the following two agency upgrades: 1) Retro Extendable Antenna - Increases Scan Range (Lvl 6); 2) Dark Matter Resonance Detector - Scanning can now find nearby Crystal Shards (Lvl 18).
- The interactive map isn't very mobile friendly. I recommend using a desktop/laptop to view it.
In case you find any mistakes, please let me know so I can fix/improve it on the map. ;-)
