Security 51 System Requirements
Run the checkpoint smoothly on Steam — Windows and macOS.
Security 51 launches on Steam August 12, 2026 for Windows and macOS (App ID 4246860). Alawar lists modest minimum specs suited to a document-heavy horror sim rather than a ray-traced action title. This page copies official Steam requirements as of launch week and adds practical performance notes for guards who stare at small ID numbers for hours — a real issue in demo streams where pixel font modes strain eyes.
Always confirm the live Steam store page via Official Links before upgrading hardware; specs can change in day-one patches noted in Launch Patch Notes.
Windows minimum requirements
| Component | Requirement |
|---|---|
| OS | Windows 10 64-bit |
| Processor | Intel Core i5-6400 or equivalent |
| Memory | 8 GB RAM |
| Graphics | AMD Radeon RX 550 or NVIDIA GeForce GTX 960 |
| Storage | 2 GB available space |
| Notes | Steam lists “Stay Hydrated” as an additional note |
Windows 10 64-bit aligns with most indie Steam releases in 2026. The GPU floor is entry-level — integrated graphics may struggle; test the free demo (App 4351470) before buying if you are on old laptops.
macOS minimum requirements
| Component | Requirement |
|---|---|
| OS | macOS Big Sur 11.7.10 or newer |
| Processor | Apple M1 or equivalent Intel Mac meeting Steam notes |
| Memory | 8 GB RAM |
| Storage | 2 GB available space |
Apple Silicon Macs generally exceed minimum CPU needs. Intel Macs near the OS cutoff should verify demo performance on your exact model.
Supported languages (Steam)
Security 51 ships with interface and subtitle support for eleven Steam languages: English, French, German, Spanish (Spain), Portuguese (Brazil), Russian, Simplified Chinese, Traditional Chinese, Korean, Japanese, and Polish. Full audio language coverage may vary — check Steam language table at purchase.
This wiki supports English, French, German, and Spanish for guides — see locale switcher. Wiki language coverage is independent of in-game UI.
Storage and install size
Two gigabytes available space is the official minimum. Leave extra room for saves, Steam cloud sync, and future patches. Playtest updates warned old saves could corrupt after major builds — budget time to reinstall rather than disk space alone.
Performance tips for checkpoint play
Demo players report readability issues with pixelated number fonts on some settings. If available, switch to clearer text modes in options — community footage shows normal text easing ID comparisons. Lower resolutions can sharpen UI on small monitors.
Controller support is confirmed — see Controller Controls if mouse precision fatigues you. Keyboard users should learn Hotkeys for Shift desk toggles.
Close background capture tools if frame drops appear during X-ray animations — X-Ray Scanning benefits from stable framerates when silhouettes matter.
Platforms not listed
Steam page lists Windows and macOS only. No Linux or console requirements appear on the store at launch. This wiki updates if Alawar announces additional platforms.
Demo versus full game
The demo uses the same engine build family as early full release. If the demo runs on your PC, the full game should meet similar performance — Demo vs Full Game. Demo is the best free benchmark.
Mature content note
Steam includes a mature content description for body scanner scenes showing partial nudity as gameplay mechanics — not sexual content. System requirements do not change; content filters are parental, not hardware.
