Good news for gamers who've been eyeing Valve's upcoming Steam Machines: Unreal Engine 4.1 will support the Linux-based SteamOS after a pending update. In a blog post today, Epic Games' Mike Fricker announced that the source code now includes "initial support for running and packaging games for Linux and Steam OS." This means that upcoming UE4 titles like Daylight and Fortnite could be ported to the systems. If you'll recall, CryEngine -- the game engine that powers the likes of Ryse: Son of Rome and others -- added Linux support back in early March to prep for the launch of Valve's newfangled platform.
