In Wolfenstein Youngblood you will be able to complete several story missions and many side quests. They take place in several locations available in the game. Most of the locations will be visited many times, so you can safely explore the area and look for collectibles.
Can I repeat the mission?
Yes, you can repeat missions that you have already completed. This allows you to return to all locations and receive new rewards. Each mission is rewarded in the same way as before – with the same amount of points and money.
To repeat the mission, you must go to Abby and select the quest you are interested in. In this way, you can constantly develop your character and watch more interesting stages of the game.
How can I get back to the place?
Upon completion of the mission, you can return to most locations. The only exception is where you complete your first mission in the game. You can’t go back to this. Examine it carefully because you can find two collectibles in it.
To go to another place, you need to go to the metro map and select the area you are interested in.
Opponents respawn?
Yes. All places previously cleared of enemies will be revisited by the Nazis as these filthy monsters are respawned as ants. You must be careful every time you return to the specified location. You can never feel completely safe!
You can find more detailed information about the enemy respawn mechanism on a separate page of our guide.
