Microsoft's Xbox Series X and S have brought forth an array of games that push players to their limits. Among these, several titles stand out for their particularly challenging gameplay. This article ranks the six hardest games published by Microsoft for these consoles, from the engaging yet demanding Psychonauts 2 to the intense survival challenges of Grounded.

6. Psychonauts 2

Psychonauts 2, released after a 16-year wait, retains the challenging essence of its predecessor. Players step into the shoes of Raz once again, navigating through thirteen diverse levels that require strategic use of his powers. The game's difficulty spikes are notable in boss battles, particularly with Die-Brarian and the Gluttonous Goats. While an Invincibility Mode is available to mitigate difficulty, the game without this aid offers a substantial challenge, balancing manageability with demanding gameplay.

5. Sea of Thieves

Sea of Thieves presents a formidable challenge, especially when played solo. Players must manage multiple ship duties while warding off threats like Skeleton Ships and the Kraken. The game's immersive design necessitates constant vigilance, and its grind-heavy nature can make acquiring loot from tougher enemies a strenuous task. While co-op play eases some of the difficulty, the game's solo experience is notably challenging due to its design.

4. Ori and the Will of the Wisps

Ori and the Will of the Wisps, the sequel to Ori and the Blind Forest, elevated the series' difficulty. Early game challenges are pronounced, with Ori facing multiple enemies without advanced skills. Skill selection plays a critical role in managing the game's demanding platforming and combat sections, with certain abilities offering distinct advantages. The game requires careful skill management and potentially external guidance to navigate its more challenging aspects.

3. Gears Tactics

Gears Tactics, diverging from the series' typical third-person shooter format, is a turn-based action game with challenging mechanics, notably permadeath. Players control various COG characters and units, each with unique skills. However, the loss of these units is permanent if they fall in battle. The game also features formidable boss battles, with the Corpser in Act 2 being a particularly notorious hurdle for many players.
