Sovereign Tower demo, Windows and SteamOS requirements
The demo link, Windows hardware tiers and separately read SteamOS/Linux requirements.
Answer: Sovereign Tower's Steam listing links a demo with appid 4422320 and supplies separate Windows and SteamOS/Linux requirements. It is listed as single-player; the current US-English full-game release date is 7 August 2026.
Demo and full game are different records
The full game uses appid 4113940. Its official listing links the demo, appid 4422320. Soundtrack and artbook entries are additional content, not separate games or proof of demo save transfer.
Windows requirements
Minimum: Windows 10, Core i5-4670K, 4 GB RAM, GeForce GT 1030 with 2 GB VRAM, DirectX 12 and 3 GB storage.
Recommended: Windows 11, Core i5-9600K, 8 GB RAM, GTX 1060 with 6 GB VRAM, DirectX 12 and 3 GB storage. These are listed tiers, not frame-rate measurements.
SteamOS and Linux tab
The separate tab lists SteamOS 3.8.10, a Zen 2 4-core/8-thread CPU at 2.4–3.5 GHz and 8 RDNA 2 compute units at 1.6 GHz. Minimum memory is 4 GB; recommended memory is 8 GB. Both tiers list 3 GB storage.
Those entries describe the published SteamOS target. They do not certify every Linux distribution or hardware combination.
Controller and handheld boundaries
Steam currently displays full controller support and a Verified Steam Deck badge. That badge is a platform assessment; we have not independently measured battery life, text legibility or frame rate.
Release-date scope
The current US-English listing shows 7 August 2026. An older archived snapshot recorded 6 August; the current record follows the live listing without asserting why the difference occurred. Platform-specific or worldwide release differences are not inferred.
