Evaluation

ZERO PROTOCOL launched on September 26, 2024. At launch, the developer noted plans to address bugs and add more content. Over the following months, several patches improved gameplay, enemy placement, controls, and performance. The most significant post-launch content update arrived on September 8, 2025 (v1.2), which added a fifth ending, ending descriptions, and the ability to replay from any previously completed level — representing a meaningful expansion of the game's content. However, the developer's August 5, 2025 announcement makes clear that their primary focus had shifted to a new project, Waterpunk: Through the Rust, which they had been developing for nearly half a year. They noted they hoped to release the ZERO PROTOCOL update "in the fall," which aligns with the v1.2 release in September 2025. By January 29, 2026, the developer released the Waterpunk demo — with no further communications about ZERO PROTOCOL since the v1.2 patch. There are no unreleased DLC listings, no announced future content for ZERO PROTOCOL, and no developer statements indicating further updates are planned. The v1.2 update appears to represent the conclusion of post-launch support, with the developer now focused entirely on their next game. The game is a self-contained single-player experience that has received its final content additions.
Evidence
v1.2 update ships a fifth ending, ending descriptions, level select for replays, and various gameplay improvements — the most substantial content addition since launch.
