Mortal Shell II: 70GB, no stamina, and a much larger world to keep running

The storage footprint explains part of the sequel's scale

Mortal Shell II requires 70GB on PC. The number is not a performance metric, but it is a useful contrast with the much smaller original and the radically expanded amount of world content.

The sequel now presents an interconnected open world, eight playable Shells and, according to the PlayStation listing, more than 80 dungeons.

An SSD is mandatory

Steam lists 16GB of RAM, a Core i7-10700K or Ryzen 5 3600, and an RTX 2060 Super 8GB or RX 6600 8GB as minimum PC hardware. DirectX 12 is required and solid-state storage is explicitly mandatory.

PS4 and Xbox One are gone entirely. Mortal Shell II targets PC, PS5 and Xbox Series X|S, while the PlayStation version is also marked as PS5 Pro enhanced.

No stamina requires different animation priorities

GameSpot notes that combat animations are substantially snappier than the original while retaining the weight of attacks that cannot simply be cancelled.

That balance is central to the technical feel. The player can chain more actions without downtime, but weapons still need convincing inertia, impact audio and enemy reactions. GameSpot particularly praises the physical brutality of strikes and the variety of weapon behaviours.

Performance depends heavily on settings

PCGamesN tested Mortal Shell II on Valve's Steam Machine and reports strong results at the base configuration. High graphical settings caused performance to deteriorate sharply on that hardware.

It is only one test system, so it should not be stretched into a universal performance claim. It does at least demonstrate useful scalability below a high-end desktop.

Technical faults can interfere with Soulslike rules

PCGamesN encountered a bug where dropped progression currency spawned outside the playable area after death. That is considerably more serious than cosmetic clipping in a game whose death loop depends on giving the player one opportunity to retrieve lost resources.

The review build preceded the day-one patch, and Cold Symmetry has already continued updating the game. Its first substantial balance patch changed currency rewards, forging costs, weapons and several bosses.

Vertical level design creates its own failure state

GameSpot praises the density of the interconnected world but also identifies an unusual recurring problem: knockback attacks and abundant cliffs result in frequent deaths from falling.

The geometry creates dramatic layered spaces. It also occasionally becomes a more dangerous opponent than the creature standing in front of the player.

This is no longer a cross-generation project

The official PlayStation listing confirms PS5 Pro enhancements and DualSense vibration support, while Playstack restricts the console release to PS5 and Xbox Series X|S.

Mortal Shell II is therefore a materially larger technical project than its predecessor, not simply a denser version of the same small-world framework.
