Seabun is an action indie casual game for PC in which players control a scientist bunny piloting a small armed submarine through progressively deeper corrupted ocean zones. The core experience centers on repeated short dives that combine auto-firing weapons with resource management and long-term progression systems.
Gameplay
The central loop involves descending through infested waters in a submarine equipped with an auto-firing loadout. Oxygen limits each dive, forcing players to maximize damage output before returning to the surface. Weapons such as harpoons, torpedoes, buzzsaws, and lasers activate automatically, allowing focus on positioning and survival amid enemies and hazards. At the end of each depth, a boss encounter awaits.
Resources collected during dives fund upgrades between runs. A large upgrade tree offers unlocks and challenges, while a workshop lets players craft and improve modules. Builds evolve from basic setups into powerful arsenals capable of clearing large areas. The lab serves as the hub for progression, where eggs are hatched, fish are fed and raised, and evolved mounts become available for future dives. These mounts alter movement and approach options. Fish continue generating pearls passively even when the player is offline.
Game Modes
Seabun features a single continuous progression system built around repeated dives of increasing depth. Each run functions as a self-contained challenge with its own oxygen timer and enemy encounters, yet carries forward permanent improvements from prior attempts. The structure emphasizes incremental power growth rather than separate named modes, with bosses marking the conclusion of each zone.
Progression and Upgrades
Between dives the lab provides several interconnected systems. Players spend earned resources on a sprawling upgrade tree that includes both statistical improvements and specific challenges. The workshop supports module crafting and enhancement, enabling customization of the submarine's capabilities. Aquarium management adds an idle element, as raised fish produce ongoing income and unlock rideable forms that modify dive strategy.
Weapon variety encourages experimentation across runs. Different loadouts suit varying enemy patterns and boss mechanics, while the upgrade tree rewards consistent play by unlocking new options and refinements.
Is It Worth Playing?
Seabun suits players who enjoy bite-sized action sessions paired with meaningful long-term progression. The combination of auto-firing combat, upgrade trees, and fish-based idle mechanics creates a loop that rewards repeated dives without demanding extended sessions. Those who appreciate incremental build crafting and passive collection elements will find the systems engaging. The game remains in active development with its core features intact, making it a solid choice for fans of indie action titles focused on depth and repetition rather than narrative or multiplayer elements.
