Aviassembly

Aviassembly is an immersive 3D flight and construction simulator developed by Jelle Booij. Set in a vast open world filled with islands, airfields, and secrets, players take on the role of aircraft designers, building planes from scratch in a dedicated workshop. Each part choice directly impacts flight physics, range, and payload capacity, emphasizing functionality over mere aesthetics. The game features two modes: career mode, where players manage resources, complete transport or firefighting missions, and earn money to unlock advanced technologies; and creative mode, which offers infinite resources for unrestricted experimentation. Players can design airplanes, seaplanes, or land vehicles, explore archipelagos, transport tools and cargo, upgrade engines and modules, and customize with unique paints and decals. Realistic physics simulation is key, such as tail-heavy designs making level flight impossible, encouraging players to test aircraft on short flights before attempting long journeys.

Core gameplay revolves around aircraft design and flight simulation. Players select parts (e.g., wings, engines, fuel tanks) in the workshop to build planes, with each component affecting flight physics like stability, speed, and payload. The game offers two modes: in career mode, players complete specific tasks (e.g., transporting cargo or firefighting) to earn resources, unlock new technologies, and upgrade aircraft; creative mode allows unlimited resources for free building. Players explore an open world, discover hidden locations, take off and land at various airfields, and challenge short runways. The game includes a technology tree for upgrading engines and modules, as well as paint customization. Physics simulation is crucial, requiring balanced designs to avoid crashes, and players must master takeoff and landing techniques.
