Infinifactory is a sandbox puzzle game by Zachtronics, the creators of SpaceChem and Infiniminer. Build factories that assemble products for your alien overlords, and try not to die in the process.

Released in 2015, Infinifactory usually costs $24.99 to purchase when it’s not on sale.

You can grab a copy from the Epic Games Store for the low, low price of free. The store has already revealed next week’s freebie too, with Doors – Paradox, a relaxing puzzle escape game, incoming to replace the latest promotion on February 1.
