They Are Billions supports mouse and keyboard on Xbox

[Windows Central]

Upcoming zombie-battling RTS They Are Billions has full keyboard and mouse support on Xbox One.
They Are Billions is a cult-hit zombie apocalypse RTS set in a steampunk future, where humanity clings to a bleak existence in a dark world plagued by, quite literally, billions of zombies. The game is a success story on Steam, enjoying a large following and plenty of free updates, including a sizeable campaign mode which recently hit the PC version.
As a strategy game with fairly complex gameplay, it remains to be seen how well the game translates over to regular gamepad controls. If you don't fancy playing that type of game with a controller, thankfully, They Are Billions will also support mouse and keyboards on Xbox One.
