Your most important objective in the seventh mission of Sniper Elite 5 is reaching the Dome in the northern part of the map. Our guide contains a walkthrough on how to infiltrate the Dome (three different ways inside) and how to obtain the Kraken plans from the war room.
Reaching the Dome
The Dome is the largest building in the mission, found in the northern part of the map. There are several ways to get inside.
The most obvious way in is the main entrance on the south of the Dome - that's where the road leads. The entrance is well guarded and there's a sniper on a tower nearby.
One of the alternate entrances is a way east of the Dome. You can reach it by using the upper exit in the neighboring Weapons Lab. There's also a Master Dome Key inside the building. You can also blow up the door with an explosive.
The second alternate entrance is also the most difficult to find. It requires you to go through the V2 refueling station, the underground complex south of the Dome. Inside the station you'll find a long, spiral staircase ending with a door leading to the Dome. You can take the key off one of the enemies or blow up the door.
Investigating Operation Kraken
The Dome is large and has several floors. We recommend using stealth takedowns and silenced weapons in order to not alert the entire area.
Use your binoculars to locate an elite sniper nearby. Either sneak past him, or, as we recommend, take him down quietly.
You don't need to explore the entire building. You can complete the mission objective by finding the war room in the north-western part of the Dome, on the upper floor, as pictured above.
You'll find the Kraken plans inside - examine them to trigger a cutscene and complete the objective.
