What is "infinifactory"

Infinifactory is a puzzle video game developed and published by Zachtronics Industries, released on June 30, 2015. The game was later released on PlayStation 4 in December 2015. In the game, the player takes the role of a human abducted by aliens and forced to construct assembly lines to create certain objects for apparently-nefarious purposes. The game combines elements of Zachtronics' previous SpaceChem and Infiniminer, with the assembly lines being built from blocks in a three-dimensional space.
