Security 51 Guide is an independent English fan guide for Security 51, an Area 51 checkpoint horror simulator developed and published by Alawar.
What this site does
The site collects release, platform, requirements and gameplay reference notes in one place. Each claim is checked against a named source and dated so readers can distinguish current facts from details that still need a live-build check.
How information is checked
Primary references include the official Steam store page, Alawar's official game page, the official Steam Community FAQ and the official launch trailer. A dated playtest report is used only where it is identified as a secondary source.
What is intentionally absent
The guide does not publish unofficial downloads, codes, exact endings, daily thresholds or unverified anomaly lists. Those details require a reliable official source or a reproducible current-build record.
Independence
This is a fan-made reference site. It is not affiliated with or endorsed by Alawar, Steam, Epic Games Store or GOG.
