General Tips
- Duel Wielding not only looks awesome, but it's also a great way to take down some tougher enemies.
- Use stealth to your advantage, especially with enemy commanders. Killing them without being detected reveals collectibles on the map.
- Explore every level thoroughly so you can find collectibles. There are a lot of them out there. You'll also find some more health and armor along the way.
- Lots of enemies are heavily armored, but not many can deal with well-placed headshots.
- Some enemies have weakpoints that are not the head; don't assume aiming for the head is the best strategy.
- Upgrade the Laserkraftwerk and relish in its power.

Easter Eggs
Wolfenstein 3D
Play the game for a few hours. Once you arrive at the headquarters of the resistance movement, go to the top floor and there will be a mattress on the ground. It is just left of the bullseye hanging on the wall. Focusing on the mattress will give you the option to enter a "nightmare." Enter the "nightmare" and you will find yourself in the very first level of Wolfenstein 3D!
