Infinifactory

In a story-driven campaign, you play an engineer abducted by aliens and put to work assembling products for them. The campaign spans more than 50 puzzles set across alien locales.

In a first-person 3D environment, place blocks to build factories that move and transform components into required products. Puzzles allow different designs, and moving parts can push or fall into place as your factory runs.

After completing a design, you can refine it by reducing its parts and footprint or improving its cycle time. Beyond the campaign, a sandbox and Steam Workshop support creating and playing custom puzzles.

Players often enjoy the demanding, absorbing puzzles and the satisfaction of getting a factory design to work. Reviews also value the freedom to find different solutions and optimize them, with some praising the atmosphere and story. Others find the difficulty, trial-and-error timing, or building in 3D frustrating.
