Er, dunno where you guys get news from sources wise, but I heard of Unturned plenty. Knew about it before it ever launched on Steam EA, when the developer basically redid the game's graphics (yes, he redid them lol) to make it look better than it did.
Also, for those of you who seem to hate F2P games with a passion - there are some F2P games done right out there. Path of Exile comes to mind first of course, but there are others. Tera is a great F2P game (and is coming to Steam soon-ish) as well.
