Check your platform against the listing
| Platform | Minimum information shown on Steam |
|---|---|
| Windows | Windows 10, 2.0 GHz processor, 1 GB RAM, 512 MB VRAM, 256 MB storage; 64-bit processor and OS |
| macOS | macOS 12, Apple M1 or 2.0 GHz Intel, 1 GB RAM, 512 MB VRAM, 256 MB storage |
| SteamOS/Linux | SteamOS or a modern Linux distribution, 2.0 GHz processor, 512 MB VRAM, 256 MB storage |
These are the developer's listed minimums, not benchmarks or a guarantee for every hardware configuration. Do not infer an unlisted Linux RAM requirement from the Windows row.
Steam Deck and input support
The store marks the game Steam Deck Verified and lists full controller support. The developer's September 17 announcement also records the Verified status. This does not establish a particular frame rate, battery duration or ideal graphics setting for every device.
Check the current Steam compatibility panel if those details matter to your purchase. This guide does not invent performance measurements.
Use verified official links
The full-game store page links the website, Discord and YouTube channel. This fan guide is independent of the developer. We have not established an official subreddit and do not label an unrelated community as one.
Before you follow an older guide
Confirm whether it is about the Demo or the release. Their advertised weapon, File and Plugin counts differ. See the Demo comparison for that distinction, then use the Beginner guide for the core loop.
