Zet Zillions

Every run in Zet Zillions is built around a fusion system that lets players combine cards together, producing over 100 distinct effects — some devastating, some embarrassingly useless. Developed by OTA IMON Studios and released May 23, 2024, it is a story-driven deckbuilder set in a randomly generated space environment where the protagonist Foam Gun pilots a planet-ship called Baby Violence on a mission to find a place where what remains of the human race can survive.

Runs take place across procedurally generated galaxies dotted with locations to scavenge, hidden portals, and characters who offer side quests. The central combat conceit involves overpopulating planets by hurling crew at them until they explode, a mechanic the game leans into fully rather than treating as a curiosity. Players build multiple deck strategies within a single run rather than committing to one, and the fusion system is the engine that ties those strategies together — combining two cards can unlock spectacular synergies or reveal a bluff that does nothing useful, making every fusion a calculated risk.

• Fusion system with over 100 card combination outcomes
• Randomly generated galaxies with scavengeable locations, portals, and NPCs
• Side quests and a story-driven narrative framing each run
• Multiple deck archetypes built and managed within a single run
• Planet-destruction as a core combat mechanic, not just flavor

OTA IMON Studios shipped several patches in the weeks immediately after the May 2024 launch, stabilizing the release through versions 1.1 to 1.3. The first substantial content update arrived in July 2024 with the Nix Arc (Patch 1.5), adding new story material. A Chaos Mode entered beta in August and September 2024 and rolled out fully to all players in February 2025, representing the most significant post-launch expansion of the game’s systems to date.

OTA IMON’s previous game, Wolfstride, is set in the same universe, and the studio notes it offers additional context — though no familiarity with it is required. Zet Zillions will appeal most naturally to deckbuilder players who want narrative texture and systemic unpredictability in the same package, particularly those who enjoy builds that can collapse spectacularly as often as they triumph.
