Evaluation
Sonar Shock launched on May 24, 2024 as a complete, self-contained horror dungeon crawler. Following launch, the developer (a solo developer, Raphael Bossniak) shipped a series of bug fix and quality-of-life patches through version 1.5 (August 29, 2024), plus a beta test in November 2024 for an engine upgrade to Godot 4.3. None of these post-launch communications announce new content, expansions, or a roadmap — they are all maintenance and polish updates. There are no unreleased DLC listings on the store, no season pass, and no developer statements indicating future content additions. The store description presents the game as a complete experience. The last developer communication was on November 26, 2024, and the absence of posts since then is consistent with a finished product rather than an interrupted development cycle — the developer never established a pattern of ongoing major content releases.
