Thomas Was Alone's DLC content, the former Playstation 3 exclusive Benjamin's Flight, is now available for free on Windows PC, Mac and Linux.
The pack tells the tale of young Benjamin, who "goes in search of the Fountain of Wisdom aided by his father's incredible invention". Included are twenty new levels, a new 'jetpack' ability and three new characters.
"Benjamin's Flight takes place before the events of Thomas Was Alone, and tells the story of the first AI to discover something very dangerous: Hope. Armed with a new jetpack ability, he'll go hunting for the strange glowing light he's long admired from afar," reads the pack's official description.
Thomas Was Alone is currently 60% off on Steam. The new content will be downloaded automatically.
