Sunshine Heavy Industries (v1.3.2)

Sunshine Heavy Industries turns spaceship construction into a cheerful engineering puzzle where every client request threatens to become a magnificent pile of expensive debris. Set in a scrappy, oddball corner of space, the game casts you as a shipyard designer working for strange customers, unreliable business associates, and pirate-adjacent locals with very particular needs. Its tone is playful and character-driven, but the design problems become seriously demanding as contracts pile on restrictions involving cost, size, power, weapons, propulsion, and survival. Rather than chasing a single correct blueprint, it rewards a ship that works, looks good, and reflects your own questionable industrial philosophy.

Each mission begins with a new commission and a list of requirements, then hands you a two-dimensional workshop full of hull pieces, engines, reactors, cargo modules, weapons, utility systems, and specialized components. You snap parts together, route the ship around physical space limitations, and balance the demands of its machinery until the design meets the contract. Early jobs teach the basic logic of assembly, while later assignments ask you to manage more interconnected systems and solve problems with increasingly clever layouts. More than 100 parts and numerous subsystem types give experimentation real weight, so rebuilding an awkward design is often as satisfying as producing a first successful draft.

What makes it stand out is its combination of open-ended construction and a light comic-story campaign instead of the dry, spreadsheet-heavy mood common to engineering games. Over 50 missions provide a substantial progression path, while extra post-campaign challenges and daily leaderboard runs give skilled builders reasons to keep refining their layouts. The colorful presentation and deliberately silly cast make failures easier to laugh at, even when a design collapses under one tiny overlooked condition. Fans of Zachtronics-style optimization puzzles, Kerbal Space Program’s trial-and-error design spirit, or vehicle builders like Besiege should feel at home; newcomers can enjoy the approachable early contracts, while veterans will appreciate the freedom to chase elegant, absurd, or ruthlessly efficient solutions.
