Last week, Wolfenstein 2: The New Colossus dropped a modest patch that re-enabled Steam overlay and sorted distribution issues in a number of regions. Today, the alternate timeline shooter has launched its first major update—that comes with a new DLC episode, ten new combat simulations, and a number of stability fixes, among other things. 

Live now, the patch activates the Vault option which was previously locked in the game's menu. Within, players will now find ten new so-called "combat simulations" that can be accessed following Chapter 2. "You can replay these missions anytime from the menu option," reads this Steam community update, "or in a room on Evas Hammer in the game."
