Giantess Naval Defense, an upcoming real‑time strategy game where players control a giant orca girl to fend off kaiju attacks, is confirmed for a Steam release in 2027 according to AUTOMATON West.

The game places players in command of a massive marine mammal avatar tasked with protecting coastal cities from towering sea monsters. Core gameplay involves building defenses, managing resources, and directing the orca girl’s abilities against incoming threats.

While specific mechanics remain under wraps, the announcement highlights a unique premise that blends naval defense with giant‑scale combat. Fans of strategy titles may find the concept appealing due to its unusual protagonist and setting.

AUTOMATON West notes the title is targeting a 2027 launch window on Valve’s Steam platform, with no further information on pricing, editions, or an exact launch date provided at this time.

As the release is still several years away, the developer has not shared a roadmap or beta schedule. Interested players can follow the store page for future updates once more specifics become available.
