Denki and Curve Digital have released the Industrial Revolution expansion for “playful programming and colonisation” sim Autonauts.

The free add-on shifts the game’s emphasis towards the mining of coal and metal resources, with players able to create advanced railroad networks and new Mk 3 Bots.

The expansion also adds mod support, with players able to upload and download custom scripts, upgrades, buildings and other content to the game via Steam Workshop.

Autonauts is the latest title from Gary Penn, former creative director at Grand Theft Auto and Lemmings studio DMA Design.

The game sees players visit procedurally generated planets and harness their natural resources to build an army of programmable AI helpers to aid their colonisation efforts.

Penn said of the latest expansion in a statement: “Who doesn’t love trains? I know I do! And I’m sure Autonauteers old and new will too… Can’t wait to see what joyous madness they make with their automated railways – not to mention the modding!

“There’s so much good stuff in our first big update: so many new things to play with and new ways to play and a whole bunch of lovely improvements, many of those inspired by the ever-awesome Autonauts community and their votes on the public suggestions list.”
