Sinking City 2 - All 3 E.R.C. Boxes in Chapter 3 - Complete EASY Guide

All three E.R.C. boxes in Chapter 3, and these are the ones actually worth going out of your way for, because each pays out something you keep rather than a note to read.

The first expands your inventory by two slots, which matters more than it sounds this early. The second is a shotgun part you can equip. The third is a Dream Essence.

The inventory box in particular is worth grabbing before you start hauling quest items around, so do this sweep early in the chapter rather than late.

The rest of the Chapter 3 collectibles are linked below.

01:29 Box 03 of 3, Dream Essence
