How to unlock the It's Time for Soup achievement in Styx: Shards of Darkness - Definitive Guide
As the trophy description states, there are Vials of Acid that you can find or craft in the game. The Prologue mission (very first one) has a tutorial Vial of Acid that is along the path you must take to progress to the end. However, you must pick up the Vial of Acid for the tutorial box to pop up. Right next to it is a dead body that was already there. Alternatively, you can do this anywhere else in the game when you already have a Vial of Acid and a dead body.
Pick up the Vial of Acid, press on the D-pad, select the Acid Solution, stand over the body then press to make a Quick Save. Press to dissolve the body, wait for the circular save icon to stop spinning in the top right of your screen, then Load Last Game from the main menu to do it again. It took me 2 minutes 30 seconds to do this 10 times. The trophy will unlock immediately.
Vials of acid are bright green flasks that can typically be found around the many zones within each mission. Much like amber vials, however, they are very rare to find and you are better off creating your own at crafting stations. Before you can create acid vials, though, you must first unlock the Acid Solution skill in the Alchemy talent tree.
Once you have access to acid vials, simply select them from your inventory by pressing and then you can dissolve enemy bodies by tapping when standing/crouching over their corpse. This achievement will finally unlock once you have dissolved ten enemy bodies over the course of your playthrough.
NOTE: This achievement can be grinded out quickly in the Prologue when you pick up your first vial of acid and the game notifies you of their usage/importance. Once you pick up the item, create a manual save and then use the vial of acid on the body right in front of you. After the corpse dissolves, reload your save and continue repeating this process until the achievement unlocks.
