Castronauts is an action indie casual game built around online co-op fishing with platforming elements. Players take on the role of Castronauts, spacefaring anglers who extract fish from hazardous alien planets while managing survival against monsters and environmental threats. The experience supports solo play or teams of up to six through proximity voice chat, with a focus on extraction objectives that must be completed before planetary collapse.
Gameplay
The core loop centers on traveling from a central spaceship to uncharted planets in an unknown solar system. Teams or solo players navigate procedurally generated environments across three distinct planets to harvest specific quantities of fish requested by an anonymous collector known as the Aquarian. Platforming allows movement through toxic depths filled with obstacles, while proximity voice chat enables real-time coordination among players in close range.
Survival requires constant attention to alien monsters that appear throughout the worlds. These creatures add direct threats alongside hazards like unstable terrain and collapsing conditions that intensify as time runs out. Players collect useful items during trips, which can be crafted into tools for defense or traded for advantages. A skill tree provides upgrades to stats such as mobility, resilience, or extraction efficiency, encouraging repeated runs to refine character builds.
Additional systems include a fish encyclopedia for tracking catches and an aquarium collection for displaying acquired species. Character customization options let players personalize their Castronaut appearance before heading out. The combination of fishing mechanics, platform navigation, and combat against creatures creates a loop where preparation and quick decisions determine success on each planet.
Game Modes
Castronauts emphasizes cooperative extraction sessions that scale from solo attempts to full groups of six. In team play, proximity voice chat supports close-quarters communication as players divide tasks like scouting, fishing, and defending against threats. Solo mode removes the chat element but retains the same planetary objectives and survival challenges.
Each session revolves around reaching a target fish count on a given planet before the environment becomes untenable. Procedural generation ensures varied layouts across the three available planets, altering obstacle placement and creature encounters on every visit. No separate competitive or versus modes are present; the design stays centered on shared extraction goals whether played alone or with others.
Progression and Systems
Item crafting forms a key layer beyond basic fishing. Found resources convert into defensive or utility items that help counter monsters during extraction runs. The skill tree expands options over time, allowing targeted improvements that make later planets more manageable. These systems reward consistent play by building a stronger Castronaut capable of handling tougher conditions.
Collection features extend engagement past individual missions. The fish encyclopedia logs every species encountered, while the aquarium serves as a personal showcase of successful hauls. Together they provide long-term tracking that complements the immediate pressure of planetary deadlines.
Is It Worth Playing?
Castronauts targets players who enjoy co-op extraction games that blend light platforming with survival elements in a casual action package. Its emphasis on teamwork through proximity chat and shared objectives suits groups looking for coordinated sessions without complex controls. Solo players can still engage with the same core loop, though coordination benefits shine brightest in groups.
The game remains in a pre-release state with no completed user reviews or extensive update history available yet. Those interested in the described mechanics of fishing under pressure, monster avoidance, and upgrade progression may find value once it launches on PC. Availability will determine accessibility, but the verified feature set aligns with fans of indie co-op experiences focused on extraction and light crafting.
