Intervalometer

Intervalometer is a science-fiction adult role-playing visual game built around detailed 3D renders and a carefully written storyline. You play as a talented young college graduate whose life is thrown off course when an unexpected event pulls him into a conflict that could decide the universe’s fate. From there, you step into the role of a capable atmospheric agent and set out to stop an alien invasion.

Along the way, you’ll meet a wide range of female characters—each one distinct in personality and equipped with their own skills. Expect lots of character interaction, relationship-driven moments, and puzzle-like mysteries that keep you moving forward. Take on the toughest assignments: survive uncertainty, protect others, and push through missions designed to test your resolve.

Engaging Storyline

The game is set in the near future. A young man is swept into a large-scale adventure after a run of bad luck—an adventure tied directly to the fate of everything. As the story develops, you’ll navigate a new reality as an agent of the “Atmospheric Bureau”, working to counter a threat originating from another universe.

During your journey, you’ll cross paths with many characters, some of whom may become allies, partners, or close friends. Together, you’ll work toward stopping the invasion and keeping the world safe.

The narrative is adult-focused and layered, with multiple plotlines that intersect across two worlds: the real world and a cyberpunk-inspired setting.
