Steam lists 160 GB of available space and an SSD as requirements for the PC version of S.T.A.L.K.E.R. 2: Heart of Chornobyl. That is the listed free-space requirement—not a confirmed download size or exact installed-game footprint. Steam’s PC listing gives the same storage figure for minimum and recommended configurations.
How much space does S.T.A.L.K.E.R. 2 require on PC?
Steam specifies 160 GB available space and notes that an SSD is required. The listing does not say the download or installed game is exactly 160 GB, nor does it specify extra temporary space for updates. Keep at least the listed 160 GB free on an SSD before installing; the listing does not recommend a particular SSD capacity or model.
These are PC requirements. A separate current Xbox or PlayStation storage figure is not established by the cited storefront information. The Epic Games Store listing does not provide a distinct verified storage value in the available listing evidence.
Official PC system requirements
Steam publishes minimum and recommended tiers. Its resolution and frame-rate figures are targets attached to those tiers, not independent benchmark results.

How to check whether your PC meets the requirements
- Check storage: Confirm that an SSD has at least 160 GB available. This is the listed free-space requirement, not a promise about the final installed size.
- Check your operating system and components: Compare your Windows version, CPU, RAM, and graphics card with the minimum tier in the table. For Steam’s recommended target, compare against the recommended column.
- Interpret the performance targets as listing guidance: Steam associates minimum with Low at 1080p and a 30 FPS target, and recommended with High at 1440p and a 60 FPS target. These labels are not a guarantee of performance on every PC.
