Assassin’s Creed Shadows Update 1.0.6: Nightmare Difficulty and Rufino

Assassin’s Creed Shadows Title Update 1.0.6 launched on June 25, 2025; it is not an upcoming update. Its headline additions were Nightmare difficulty, which changes both stealth and combat, and the free Critical Role quest “A Critical Encounter,” which rewards a recruitable ally named Rufino. Ubisoft later said the game’s final update was available in June 2026.

What Update 1.0.6 added

Ubisoft announced the update in release notes published June 24, 2025, with a scheduled release of June 25 at 14:00 UTC / 10:00 EDT / 7:00 PT. The notes described its new difficulty as a tougher, more intense experience. Ubisoft’s Title Update 1.0.6 release notes said: “Prepare for tougher enemies and a more intense overall experience.”

The notes listed download sizes of 6.27 GB for PS5, 19 GB for Xbox Series, 9 GB for Mac, 17 GB for PC, and 8.5 GB for Steam. Those are the figures in the June 2025 announcement, not a guarantee of current download or install sizes.

What Nightmare difficulty changes

Nightmare raises the challenge across stealth and combat by making defenses less effective, enemies more dangerous and resources harder to come by. It is a difficulty setting for players prepared to adapt to tougher detection and tighter timing as well as harder fights.

#1 Best Overall
Assassin’s Creed Shadows - Limited Edition (Amazon Exclusive), PlayStation 5
  • Only at Amazon Limited Edition Content includes the base game and Sekiryu Character Pack
  • Explore the captivating open world of feudal Japan, from spectacular castle towns and bustling ports to peaceful shrines and war-ravaged landscapes. Adventure through unpredictable weather, changing seasons, and reactive environments.
  • Become Naoe, a shinobi Assassin, and Yasuke, a legendary samurai, as you experience their riveting stories and master their complementary playstyles.
  • Make information your weapon as you explore the world, and build your own network of spies to be your eyes and ears across locations to hunt down your next target. Along the way, recruit new allies with unique abilities to help accomplish your missions.
  • Create a fully customizable hideout for your growing shinobi league as you train your crew, craft new gear, interact with key characters, and choose your base’s layout, decorations, and accessories.
  • Parries and defense: A parry must be timed perfectly to deflect a hit. An imperfect parry only partially blocks damage, and enemies deal more damage overall.
  • Enemy behavior: Enemies are smarter, faster and more aggressive, including when they detect the player. Dodges and parries no longer make enemies vulnerable; abilities are needed to create that opening.
  • Stealth: Naoe can make noise while crouching and can be spotted while moving in shadows.
  • Resources: Adrenaline, rations and shinobi items are harder to obtain. The notes’ addendum specifies that kunai used on Nightmare cannot be recovered from enemies.

Choose Nightmare if you want a greater challenge in both stealth and combat and are comfortable managing scarcer supplies and more demanding parry timing. The update notes describe those changes but do not recommend a particular difficulty for any type of player.

How to unlock Rufino in “A Critical Encounter”

The free quest “A Critical Encounter” came from Ubisoft’s collaboration with Critical Role. Rufino, an old friend of Tomiko and Heiji, asks Naoe and Yasuke for help after uncovering a conspiracy. Completing the quest adds Rufino as a recruitable ally; he is based on the character played by Robbie Daymond in the Critical Role Assassin’s Creed Shadows one-shot.
