Where to Find It

Use the official Steam app page as the source of truth for current PC requirements.
Check the System Requirements section before buying because Early Access optimization can change over time.
If you are near minimum specs, compare both CPU and GPU—not just RAM or storage—before installing.

How to Use It

Treat minimum specs as “can launch and play,” not guaranteed high settings.
Aim closer to recommended specs if you plan to play co-op, explore dense biomes, or record gameplay.
Leave extra storage headroom beyond the 50 GB listing for patches, shader/cache files, and temporary downloads.
