Eurogamer's review of Mortal Shell 2 finds it a significant step up from the original, calling it an accomplished and confident Soulslike that stands among the genre's best. Where the first Mortal Shell felt like an earnest but rough indie take on Dark Souls, hampered by shallow mechanics and a weak final third, the sequel overhauls nearly every system to fulfil the promise the original only gestured towards.

The review highlights a strong opening sequence that sets an unsettling tone before reintroducing Harros, a returning Shell, and showcasing refined combat built around grounded, brutal fighting, no stamina bar, forgiving parry timing, the Resolve mechanic and new sidearms. Although set in the same world and featuring familiar Shells, the game is a standalone sequel with an entirely separate story, making it accessible without requiring knowledge of the first title. The reviewer praises its improved depth, pacing and polish across roughly 30 hours of play.
