Quick Answer
Quick Answer
The safest compatibility answer is simple: check the store page for your platform and use that as the floor. The official CBT page listed a lower beta requirement on iPhone XR / 3GB RAM and Android 8.0, but the live release listings are stricter, so they should win. On iPhone, that means iPhone XS or newer with iOS 15.0+. On Android, it means Android 9.0+, a 64-bit device, Snapdragon 855 or later, and 6GB RAM. If your phone only barely meets the floor, plan for shorter sessions and lower tolerance for effect-heavy content.
Current Official Requirement Snapshot
| Platform | Store requirement | What it means in practice |
|---|---|---|
| iPhone / iPad | iOS 15.0 or later; iPhone XS or newer; 4GB RAM minimum | Older iPhones that met the beta floor are no longer the safe assumption |
| Android | Android 9.0 or later; 64-bit; Snapdragon 855 or later; 6GB RAM | Midrange or older Android devices below flagship-2020 class are the main risk zone |
| Storage | App Store size about 1.5 GB; Game8 estimates about 2 GB free | Leave headroom beyond the raw download size for patches and cache |
Why the Store Page Matters More Than Beta Specs
The CBT floor was explicitly provisional
The official CBT page says launch requirements were subject to change. They did change, so the beta page is context, not the final install rule.
Release listings are stricter on both platforms
iPhone moved from XR / 3GB in the beta page to XS / 4GB on the App Store, and Android moved from 8.0 in beta to 9.0 on Google Play.
Performance complaints already exist in official feedback
The CBT report mentions processing overload and overheating, so barely meeting the floor should be treated as “can try,” not “will feel comfortable in every mode.”
Four Checks Before You Install
- Confirm OS version first. This is the cleanest instant pass/fail check.
- Confirm RAM and chip class second. Android especially needs the Snapdragon 855 / 6GB RAM floor.
- Leave extra storage headroom. Treat Game8’s “about 2 GB” note as the safer practical target, not just the raw package size.
- If you only barely qualify, expect to tune settings and session length. That is especially true for co-op and other visually busy modes.
Who Should Be Cautious
| Situation | Why to be cautious |
|---|---|
| Older iPhone that met beta but not the release listing | The live App Store floor is higher now |
| Android device under Snapdragon 855 or with 4GB RAM | Google Play’s published floor is already above that |
| Device with little free storage left | Even if the install begins, patches and cache can push the phone into a bad state |
| Phone that already runs hot in 3D action games | The official CBT report explicitly mentions overheating risk |
FAQ
Can I trust the CBT requirement page instead of the stores?
No. The CBT page itself warns that launch requirements could change, and the release listings are now the stricter and safer authority.
Is 1.5 GB enough free space because that is what the App Store shows?
Treat that as the package size, not the comfort target. Game8’s roughly 2 GB recommendation is the safer practical number to keep free.
If my phone meets the floor, am I guaranteed smooth co-op and shrine runs?
No. The official CBT report specifically mentions performance slowdowns, co-op connection stability, and overheating. Meeting the floor only means you are inside the supported starting range.
