Mission 3: Sonderzüge Sabotage in Sniper Elite Resistance includes an objective called "search for clues on the superweapon." It requires players to explore the hotel building and uncover clues about the superweapon that the Nazis are developing. There aren't specific quest markers once you're in the building. So, you'll have to solely rely on exploration to find the hidden documents and complete this objective. To make things easier, here's how you can find the clues.

Finding the First Clue on the Superweapon in Sniper Elite Resistance

The first thing you'll need to do is enter the hotel by taking care of enemies in the courtyard. Once they're down, head inside through the main entrance, and enter the hotel's lobby.

You'll spot an elevator shaft on the first floor, simply drop through it to enter the hotel's basement. There's a bunch of loot in this section, make sure to grab whatever you need before heading further down into the basement.

Here, you'll see some Nazi maps and documents on the wall. Take a picture of the secret Nazi documents to get your first clue about the superweapon.

Finding the Second Clue on the Superweapon on the Top Floor

Once you have the first clue for the superweapon, return to the hotel's lobby and head to the bar to grab the "Penthouse Key" from the back. After taking the key, head up the staircase to reach the top floor of the hotel.

You'll encounter a lot of Nazi soldiers along the way, so make sure to take them out quietly with either melee takedowns or a suppressed weapon. Once you get to the top of the hotel, you'll notice there's no way to reach the penthouse.

Here, look for one of the open windows in the hallway with white paint on them. You can use these windows to climb to the penthouse using the pipes on the building's exterior. After you reach the top, you'll either directly enter the penthouse from the bathroom area or use the "Penthouse Key" on a door to access it.

Either way, one soldier is guarding the last clue, so make sure to eliminate him. After the room's clear of all threats, grab the second clue from the war table to complete the "search for clues on the superweapon" in mission 3 of Sniper Elite Resistance.
