For those who prefer management simulations with a relaxed, creative edge, Megaquarium* stands out as a standout title. Developed by Twice Circled, the game blends aquarium construction with ecological balance, offering players the chance to design underwater habitats while managing staff, research, and visitor satisfaction.
The original release launched eight years ago, but the developer has consistently refined the experience. The latest update—set to arrive on February 25—marks one of the most substantial revisions yet, coinciding with the arrival of the Invertebrilliant Collection DLC, which expands the game’s roster to include invertebrates and specialized tank designs.
The update addresses core gameplay inefficiencies, particularly in the campaign mode. Director Tim Wicksteed has overhauled progression systems to reduce redundant research tasks, ensuring animals and equipment are more readily available within objectives. Research costs and prestige requirements have also been adjusted to improve pacing, with the goal of making the campaign feel more fluid for both newcomers and returning players.
Under the hood, staff management receives notable enhancements. Players can now assign priority tasks to employees, optimizing workflow in larger aquariums. Backpacks for staff have been upgraded to carry additional resources—such as gift shop supplies—while lighting systems gain flexibility, allowing placement on any tank. The most significant mechanical shift, however, is the transformation of calcium from a passive buff into a mandatory resource for species that require it, directly influencing habitat design and animal placement.
The Invertebrilliant Collection DLC introduces a diverse array of invertebrates, including corals, and expands the tank catalog with underfoot floor tanks, magnifying tanks, and wide vista tanks. These additions cater to players seeking varied aesthetic and functional options for their aquariums.
For administrators and long-time players, the update introduces finer controls over staff delegation and resource allocation, while the DLC broadens creative possibilities. The changes collectively position Megaquarium* as a more polished and expansive experience, reinforcing its appeal as a niche but deeply satisfying management sim.
Both the free update and the DLC will be available on February 25.
