The Modern Prometheus quest in Quarantine Zone The Last Check is a multi-step objective that challenges players to balance risk, resource management, and rule-breaking. Available starting on day 20 of the campaign, the quest centers on a survivor whose experiment requires materials that directly violate infection control regulations.

The quest is initiated when Stuart appears at the checkpoint carrying a zombified head hidden in his baggage. Instead of enforcing standard liquidation procedures, players must choose to admit him into the survivor block to continue the quest. This decision sets off a chain of tasks that must be completed carefully to avoid failure.

Keeping Stuart alive is a mandatory requirement. Players must ensure he is returned to the base during evacuations and protected from hunger, illness, overcrowding, and zombie attacks. Although this aspect is manageable, progress stalls unless players locate four zombie body parts for his experiment.

These body parts must be sourced exclusively from survivor baggage. Items taken from liquidation or laboratory processes do not count toward the objective. Because infected items appear randomly in survivor inventories, collecting all four parts may take multiple days and consistent inspection efforts.

Each confiscated body part results in a $100 fine, reflecting the violation of camp rules. While the total cost is manageable, poor financial planning can quickly lead to a negative balance and campaign failure. After delivering all four parts, players can speak with Stuart and allow him to proceed with his experiment overnight.

The outcome is catastrophic. By the following morning, Stuart has died, and zombies have overrun the survivor base. Players must respond immediately by eliminating every zombie inside the base using standard weapons. Once the outbreak is resolved, Stuart’s tent becomes accessible.

Inside, players can collect $500 and a black case containing a severed head collectible. Although the net profit is minimal, the quest offers narrative depth and a unique collectible for completion-focused players.
