Evaluation

100 Radioactive Cats is a free-to-play hidden object game that launched on December 14, 2025 as part of the developer's "100 Cats" series. The game shipped as a self-contained, finished product: it features a single level with 100 hidden cats to find, and its store description presents no ongoing content cycle, seasonal updates, or post-launch roadmap. All three DLC items — an Extra Content pack, a Soundtrack, and an Artbook — were released on or around launch day and no unreleased DLC remains on the store. There are no developer communications indicating future updates or expansions are planned. The game was designed and sold as a complete experience from day one.
