Loopquarium Blends Deckbuilding and Aquarium Management on Steam
Fellswell has officially revealed Loopquarium, an aquarium roguelite coming to PC via Steam... and it’s shaping up to be a surprisingly clever mix of cozy management and strategy.
At first glance, Loopquarium feels like you’re building a peaceful fish tank, collecting new species, and keeping your ecosystem balanced. But that calm doesn’t last very long. As day turns to night, your aquarium becomes a primed battleground with threats arising from the depths and forcing you to defend everything you’ve built.
The twist of this game lies in the deckbuilding system. Each fish acts like a card with its own abilities, meaning success comes down to how well you balance predators, prey, and support effects. Smart combinations, environmental factors like water currents, and knowing enemy weaknesses all play a role in surviving each run.
There’s also a steady sense of progression. You’ll unlock new fish, items, and pets over time, which affect future runs, but pushing your build too far ramps up difficulty through the Depth Meter, adding tougher enemies and higher stakes.
Whether you’re trying to collect the three egg pieces and escape or pushing deeper into Endless Mode for bigger challenges (and bosses like Poseidon), Loopquarium keeps things dynamic. And if you just want to relax, there’s a Virtual Tank mode where you can show off rare fish in peace.
Key Features:
- Over 60 fish types, 60 items, and 14 bosses, all with unique abilities
- Deckbuilding system that balances predators, prey, and ecosystem synergy
- Meta-progression with unlockable upgrades and pets across runs
- Multiple difficulty options, from Zen mode to Boss Rush
- Endless Mode and major encounters, including mythic bosses
- Virtual Tank mode to collect and display rare fish variants
Blending soothing aquarium vibes with roguelite tension, Loopquarium is one to watch if you like your strategy games with a creative twist.
