The Sega-owned studio says it will also support Valve's recently announced Steam Controller, saying the touchpad-enabled gamepad will make playing Total War in the living room possible.
"We've always wanted the Total War franchise to be enjoyed by living room gamers, but the limitations of traditional hardware made our style of game play impossible," said The Creative Assembly brand manager Rob Bartholomew. "Last month, when Valve invited us to test out the new Steam Controller and unveiled their plans for SteamOS — we were impressed. We believe it will provide us with the control fidelity and platform we need to make a living room experience for Rome 2 that could be a more compelling experience than playing with keyboard and mouse."
Total War: Rome 2 will come to Linux in 2014, with Steam Controller and Big Picture mode support "to be added as soon as Valve gets us a controller dev kit," Creative Assembly said.
Earlier this week, Deep Silver and 4A Games confirmed the Linux version of Metro: Last Light will support SteamOS and Steam Controller. Valve also confirmed that Steam Machine beta testers will get Metro: Last Light as part of the upcoming beta test.
In September, Valve promised multiple announcements related to AAA games supporting SteamOS. The company said it will unveil new details about SteamOS and Steam Machines at CES 2014 in January.
