About the developer
Sergey Vlasenko is an independent game developer who has released several mobile titles, primarily for iOS and Android platforms. Duty Stalker, a tactical first-person shooter inspired by the S.T.A.L.K.E.R. series, is among his most well-known projects.
The game was developed using Unity and features single-player missions with AI-driven enemies, a variety of weapons, and a post-apocalyptic setting reminiscent of the Chernobyl Exclusion Zone. It gained attention for bringing a console-style shooter experience to mobile devices at a time when such games were rare on the platform.
Release and reception
Duty Stalker was first released on the App Store and Google Play in the early 2010s, with updates and new versions rolling out over subsequent years. The game received mixed to positive reviews from players who appreciated its ambitious scope for a mobile title, though some critics noted limitations in graphics and controls compared to PC or console shooters.
Vlasenko continued to support the game with patches and content updates, and it remains available on major app stores as of 2026. The title has occasionally been referenced in discussions about notable indie mobile shooters and S.T.A.L.K.E.R.-inspired fan projects.
