The video above is the Ratchet & Clank 2016 That Sinking Feeling Trophy Guide and shows how to unlock That Sinking Feeling Trophy in Ratchet and Clank 2016.
This trophy can be unlocked on Aridia while looking for Skidd’s Agent. While playing this part of the mission you will encounter several constructobots.
To unlock the trophy one of them must be pushed off the platform.
You can do this by shooting them with your combuster, or by smacking them with your wrench.
If you fail, revisit the planet and at least one of them will respawn.
