How to Expand Inventory in The Sinking City 2
Find inventory upgrades in E.R.C. crates or on tables in dungeon areas and open crates with an activator pen.
Answer first
Quick Answer
Inventory space increases through inventory upgrades found inside E.R.C. crates or placed on tables in some dungeons. E.R.C. crates require an E.R.C. activator pen, which can be found in different locations within levels, so retain the pen and revisit a marked crate if you cannot open it yet.

Key Takeaways
- Inventory upgrades are found in E.R.C. crates or on dungeon tables.
- E.R.C. crates need an activator pen.
- Activator pens appear in different level locations.
- Revisit unopened crates after finding a pen.
What to Search
Do not limit the search to one container type. The official FAQ confirms both E.R.C. crates and loose upgrades on tables in some dungeons. Search side rooms and readable surfaces, then treat a locked crate as a return point rather than a dead end.
An activator pen opens an E.R.C. crate. Because pens can be found in different places on a level, continue the active route and return once equipped if the crate cannot be opened immediately.
