1. How to Complete the Hidden Secret Quest in Escape From Duckov
Hidden Secret Quest
After completing the New Cargo quest, talk to Xavier to unlock the Hidden Secret quest. This mission takes place on the Warehouse map and involves exploring two hidden cellars filled with rare loot, enemies, and toxic gas.
Completing the quest grants valuable rewards, including XP, blueprints, currency, lore items, and the Cube Storage Device — used to store and activate Blue Cubes for advanced crafting. Finishing it also unlocks the next quest in Xavier’s chain, Multi-Talented, which requires collecting unusual items like a tambourine and xylophone.
1.1 Main Objectives in Hidden Secret Quest
- Find and open two hidden cellars located around the Warehouse map.
- Collect all loot and quest items from inside.
- Return to Xavier to claim your rewards.
- Unlock the Cube Storage Device and the next quest, Multi-Talented.
These rewards are essential for crafting progression and expanding your access to new game areas.
1.2 How to Get a Cellar Key and Gas Mask
Step 1 – Find the Cellar Keys
- clothing containers
- corpse,
- or specific crates scattered throughout the Warehouse map.
Step 2 – Prepare for Toxic Gas
Before entering the cellars, make sure to equip a Gas Mask — both areas are filled with toxic gas that drains HP over time.
- You can obtain a Gas Mask through random loot drops, quest rewards, or by purchasing one from the Black Market.
- The Ravine Cellar, in particular, has heavy gas concentration, so healing items and armor upgrades are also recommended.
Step 3 – Clear the Cellars and Collect Loot
Once equipped and ready, enter each cellar, defeat the enemies inside, and loot everything — these locations often contain rare blueprints and materials used for late-game crafting.
After clearing both, return to Xavier to complete the quest and receive your rewards.
