Silent Shark Demo vs Full Game
What the free demo teaches today versus what the August 12, 2026 Steam launch adds to your patrol career.
Silent Shark offers a free demo (browser and Steam) while the full game targets Steam launch on August 12, 2026 for Windows, macOS, and Linux. Both share the core tactical attack loop; the full release adds Pacific campaign, boat progression, and expanded scenario tooling. This page helps you decide how much time to invest pre-launch.
Neither version includes multiplayer — solo command only.

Save data and progression
Demo and full game are separate Steam products. Expect separate save slots unless official announcements say otherwise. Skills transfer; career progress does not from demo to paid release by default.
Mobile versions
iOS, iPadOS, and Android ports are planned separately from the August 2026 Steam date. This comparison focuses on PC.

Purchase timing
Wishlist anytime; buy at launch if demo clicks. No paywall on learning core loop — full game buys campaign persistence and classes.
Achievement hunters
Full game targets 32+ Steam achievements per store materials. Demo achievements separate — see Launch Notes.
FAQ alignment
If you only want tutorial experience, demo suffices indefinitely. If you want Porpoise through Balao progression and historical events, full release required.
Family sharing
Standard Steam family library rules apply at launch — demo remains separate free product.
