Infinifactory is a first-person puzzle game about building assembly lines in 3D space. You're abducted by aliens and forced to construct automated factories that manufacture their products using conveyor belts, welders, rotators, and other industrial components. Each puzzle presents input materials and a target output—you design the machinery to transform one into the other. The campaign spans 30+ levels across alien facilities, with audio logs filling in your predicament. After solving a puzzle, you'll see histograms comparing your efficiency against other players, which tends to send you back to shave off blocks and cycles. A sandbox mode and Steam Workshop support let you tackle community-made challenges. If you like spatial reasoning and optimization loops, this delivers both without hand-holding.
