The Sinking City 2 ERC Crates Guide: How to Open Emergency Relief Crates
Learn how ERC Crates work in The Sinking City 2, what the activator pen does, and which rewards to prioritize.
What Are ERC Crates?
ERC Crates, or Emergency Relief Crates, are high-value containers in The Sinking City 2. They usually reward inventory upgrades, weapon parts, materials, or route-changing survival items. If you see a white or gold upgrade-style crate, do not leave the area until you know whether you can open it.
ERC Crates connect directly to exploration, Talent Points, weapon planning, and safe room loops.
How to Open ERC Crates
| Step | Action |
|---|---|
| 1 | Search nearby rooms for an activator pen, key item, or route clue |
| 2 | Read documents before leaving the area |
| 3 | Check locked doors, side halls, and upper floors |
| 4 | Return to the crate after opening shortcuts |
| 5 | Save after collecting the reward |
Some crates may be easy to see but delayed by a puzzle or side route. If you cannot open one yet, write down the location and return later.
ERC Crate Rewards
| Reward Type | Why It Matters |
|---|---|
| Inventory upgrades | Lets you carry more ammo, healing, and quest items |
| Weapon upgrades | Reduces ammo cost in future fights |
| Crafting materials | Supports long routes and boss preparation |
| Survival items | Helps before enemies, bosses, and distant safe rooms |
ERC Crates and the Activator Pen
The activator pen is the key phrase to remember. If a crate will not open, search for the pen-like item, nearby clues, or route steps that unlock the crate. The walkthrough is the best route companion.
