Mortal Shell II System Requirements Explained
Mortal Shell II requirements straight from Steam: only one official spec tier exists (no Recommended), needs 16GB RAM, RTX 2060 Super, and 70GB SSD space.
Mortal Shell II's official PC requirements, taken directly from its Steam store page, call for an Intel Core i7-10700K or AMD Ryzen 5 3600, 16 GB of RAM, an RTX 2060 Super or RX 6600 (8 GB VRAM), and 70 GB of free SSD space. There's no separate "Recommended" tier published — Steam lists a single "Minimum" spec, and that's the number to build around.
Mortal Shell II released August 20, 2026 on PS5, Xbox, and Steam, developed by Cold Symmetry and published by Playstack. It's an Unreal Engine 5 game, which explains the notably heavier footprint compared to the original Mortal Shell.
Official Minimum Requirements (Steam Store Listing)
This is the only officially published spec tier as of this writing. Steam does not list a separate "Recommended" configuration.
| Component | Official Minimum (Steam) |
|---|---|
| OS | Windows 10 / 11 |
| Processor | Intel Core i7-10700K @ 3.8 GHz or better, or AMD Ryzen 5 3600 @ 3.6 GHz or better |
| Memory | 16 GB RAM |
| Graphics | NVIDIA GeForce RTX 2060 SUPER 8 GB or AMD Radeon RX 6600 8 GB |
| DirectX | Version 12 |
| Storage | 70 GB available space |
| Additional Notes | SSD required |
That SSD line isn't a suggestion — it's listed as a requirement, not a nice-to-have. Read the storage section below for why.
No Recommended tier exists yet
Unlike most modern releases, Steam has not published a separate "Recommended" spec for Mortal Shell II — only the single Minimum tier above. If you're trying to plan for higher settings or higher framerates, there's currently no official target to build toward.
Why You Might See Lower Numbers Online
Some sites list a noticeably lower spec for Mortal Shell II: Windows 10, an Intel Core i5-10600 or AMD Ryzen 5 5500, 12 GB RAM, a GTX 1060 3GB or RX 580 4GB, and only 30 GB of storage. Do not build around these numbers — they don't match the live Steam listing and appear to be outdated, possibly pulled from an earlier build's requirements page or mixed up with the original 2020 Mortal Shell.
| Component | Outdated listing (do not use) |
|---|---|
| OS | Windows 10 (64-bit) |
| Processor | Intel Core i5-10600 (3.3 GHz) or AMD Ryzen 5 5500 (3.6 GHz) |
| Memory | 12 GB RAM |
| Graphics | NVIDIA GeForce GTX 1060 3GB or AMD Radeon RX 580 4GB |
| DirectX | Version 12 |
| Storage | 30 GB available space |
The current Steam listing is the one that matters
If a spec chart you're looking at shows a GTX 1060 or a 30GB install size, it's stale. The live Steam store page — the authoritative source — confirms the higher i7-10700K / RTX 2060 Super / 16GB RAM / 70GB spec as the real minimum.
Unofficial Upgrade Path (Not an Official "Recommended" Spec)
Because Steam hasn't published a Recommended tier, hardware retailer Corsair put together its own unofficial suggestion for players who want smooth 1440p/60fps with ray tracing enabled, given that Mortal Shell II runs on Unreal Engine 5:
- GPU: NVIDIA RTX 40-series or AMD RX 7900 XT / XTX
- CPU: Intel Core i7-13600K or better, or AMD Ryzen 5700X or better
- RAM: 32 GB
Treat this as a third-party recommendation, not a developer- or Steam-published figure. It's a reasonable target if you're shopping for an upgrade, but it isn't an official benchmark the way the Minimum spec table above is.
Steam Deck Compatibility
Steam Deck compatibility for Mortal Shell II is unconfirmed (TBD) as of this writing. No verified Deck rating or performance data was available at the time of this page's research — check Steam's own Deck Verified rating on the store page before assuming compatibility either way.
Performance Notes: What to Expect
Mortal Shell II runs on Unreal Engine 5 with Lumen global illumination, Nanite geometry, and Virtual Shadow Maps active, which is a big technical step up from the original game. Independent testing found overall performance decent but not flawless: launch-day shader compilation covers most of the early-area stutter without eliminating it completely, and traversal streaming through the game's open zones is largely smooth with occasional frame-time spikes.
A few things worth knowing before you tune settings:
- The game ships with FSR, DLSS, and TSR upscaling, but its native TSR implementation is comparatively weak, with shimmering similar to FSR 3.
- Hardware Ray Tracing currently shows no measurable visual or performance difference when enabled, and requires every other setting maxed to even turn on — leave it off.
- Nvidia Reflex is force-enabled at the engine level (even with Frame Generation off) with no in-game toggle to disable it.
None of this changes the official spec table above, but it explains why hitting a stable framerate can take some settings tuning even on hardware that clears the minimum bar.
Storage & Install Notes
Mortal Shell II needs 70 GB of free space, and Steam explicitly requires an SSD rather than just recommending one. That's roughly six times the original Mortal Shell's install size (about 12 GB), reflecting the jump to Unreal Engine 5 assets. The SSD requirement lines up with the game's background dungeon-streaming design, which loads interior areas without traditional loading screens — something a mechanical hard drive isn't built to keep up with.
