Sniper Elite: Resistance features a variety of Kill Challenges, each requiring players to eliminate specific Nazi officers in creative ways. One of the most satisfying and strategic eliminations takes place in Mission 8: End of the Line, where you must take down Hermann Gottschalk using a gas explosion. This guide will walk you through the best strategy to execute this kill efficiently and stealthily.

Step 1: Unlock the Eastern Rail Yard Start Point

Before beginning the mission, ensure you have unlocked the Eastern Rail Yard starting location. If you haven’t unlocked it yet:

1. Set the difficulty to Civilian.
2. Run to the designated point on the northern part of the map.
3. Exit the mission and restart at your preferred difficulty.

Starting from the Eastern Rail Yard allows you to complete this Kill Challenge quickly without alerting any enemies or needing to fire a shot.

Step 2: Move to the Gas Valve

1. Begin the mission and immediately move along the right-side wall to stay undetected.
2. Sprint when safe, but slow down once you approach the yellow mission marker’s outer edge.
3. There will be a single guard patrolling the area. Either wait for the right moment to sneak past or silently melee kill him.
4. Continue moving south while staying low and undetected. You will pass a crane and need to maneuver between metal stairs and a steam engine.
5. Keep heading forward until you find a small white house.

Step 3: Set the Gas Explosion Trap

1. Locate the red gas valve on the opposite side of the white house.
2. Interact with the valve to release gas pressure into the pipe.
3. Shortly after, Hermann Gottschalk will notice the leak and rush over to investigate.
4. Within moments, the built-up gas will ignite and explode, killing Gottschalk instantly and completing the Kill Challenge.

Step 4: Escape or Continue the Mission

Once the explosion occurs, you can quickly save the game to continue without raising an alarm. Since this strategy keeps enemy awareness low, you should be able to exit the area undetected and proceed with the rest of the mission.

By following this guide, you can efficiently eliminate Hermann Gottschalk using a gas explosion without engaging in combat. This method ensures you complete the Kill List Challenge stealthily and with maximum efficiency. Good luck, sniper!
