This Seeking Tech guide will explain how you can get the Pocket Stuffer trophy in Sly 3: Honor Among Thieves (2024) on PS5 and PS4.
This will unlock by doing the following: “As Bentley, drop a bomb in 5 pockets.”
Use the following video as a reference:
To drop a bomb in an enemy’s pocket, you need to sneak up behind them with Bentley. You then need to hold the Triangle button and then release it. Afterwards, stay clear of the blast area.
The trophy should unlock when you drop a bomb on the fifth enemy.
