How to get out of Sphere military base in “Behind Seven Seals” mission in Stalker 2? How to exit ISPF base in stealth during main quest

During the pivotal “Behind Seven Seals” storyline mission in Stalker 2, players must infiltrate the heavily guarded Sphere military compound to locate the NPC Solder. After completing your objective with this character, the real challenge emerges: extracting from the ISPF-secured facility while avoiding overwhelming opposition. This comprehensive guide reveals how to successfully complete this extraction sequence without engaging in a resource-draining firefight against continuously respawning enemies.

Upon concluding your dialogue with Solder, ascend to the upper level where you’ll discover yourself positioned in a corridor adjacent to the primary entrance. As illustrated in the accompanying screenshot, this main exit appears on the left side. While this represents the most direct escape path, selecting this route should only be considered if you deliberately seek combat against the entire ISPF garrison, including additional units that materialize behind your position. The enemy count will be substantial, making this approach feasible only with extensive medical supplies and disciplined ammunition conservation.

For players preferring tactical discretion over direct confrontation, an alternative covert exit strategy exists. Proceed along the right-hand corridor until you identify a compact storage area featuring a compromised wall section. This critical passage point is situated at the hallway’s terminus on the right side, providing access to the exterior with significantly reduced enemy engagement.

Expect to encounter a limited contingent of soldiers patrolling the external area. During daylight operations, these guards will detect you almost immediately, making stealth movement challenging. Employ tactical luring maneuvers by drawing them indoors where you can eliminate them discreetly. After exiting the structure, neutralize two additional soldiers positioned on the left flank. Subsequently, locate the essential ladder situated between the industrial pipelines, as clearly marked in the reference screenshot.

Once you’ve ascended, proceed toward the rooftop area, then utilize storage crates to gain elevation onto the upper surface. Be prepared to encounter several active electro anomalies atop the structure. Carefully navigate along the perimeter wall, turning right when possible. You’ll discover a passageway secured with a tripwire defense mechanism.

After successfully disarming the tripwire device, maneuver through the narrow gap separating the wall and the substantial metal container, then leap onto the pipeline network once more. From this vantage point, you can descend safely to terrain located beyond the base’s security fencing, completing your stealth extraction.

Timing and Visibility Considerations: The stealth approach becomes considerably more manageable during nighttime operations when reduced visibility decreases enemy detection ranges. If possible, coordinate your extraction during darker periods or wait for weather conditions that limit visual contact. The ISPF patrol patterns also vary based on time of day, with fewer active guards during night shifts.

Resource Optimization: Even when selecting the stealth route, ensure you carry at least two medkits and maintain your weapon in good condition. Unexpected encounters may still occur, and having backup resources prevents mission failure from minor mistakes.

Common Execution Errors: Many players fail by attempting to rush through the rooftop section without properly assessing anomaly placement. The electro anomalies follow predictable patterns – observe their activation cycles for 10-15 seconds before moving. Another frequent mistake involves inadequate soldier elimination before proceeding outdoors, resulting in alerted reinforcements.
