The price at a glance

| Storefront | Base price | Launch discount | Notes | | --- | --- | --- | --- | | Steam | $19.99 | 25% (early window) | Steam Deck Verified, AppID 2950790 | | GOG | $19.99 | 25% | DRM-free | | Epic Games Store | $19.99 | 25% | — | | Humble Store | $19.99 | 25% | — |

The discount window ended around August 20, 2026 per the official press materials — after that, expect the full $19.99. Regional pricing may differ; the US figure is the reference used in the official announcement.

Is the demo free?

Yes — a free demo was released during Steam Next Fest in June 2026. The demo is a separate product from the paid base game, so "free to play" applies to the demo only. The full game is a paid product.

Any hidden costs?

As of August 12, 2026 there are no confirmed paid DLC, season passes, or microtransactions. The Steam page advertises the base-game features (30 ammo types, 100+ medals, 15 regions) as included. Any future paid content would be 待确认 (unconfirmed) until the developer announces it.

Is there a cheaper official key?

The four storefronts above are the official sources. Grey-market key shops are not official, carry no publisher warranty, and are not endorsed — the research explicitly excludes them as sources. For the safest price, compare the four official storefronts directly; GOG is the DRM-free option if that matters to you.

Should you buy at launch price or wait?

That is a value judgement, but here are the verified facts: the game launched August 6, 2026, is single-player only, and has no Game Pass or console version. It received three patches in its first four days (Builds 1547, 1558, 1577), including a save-corruption fix — early buyers were part of that fix cycle. If you want the least early-access turbulence, the discount window still covers the first weeks.
