When the Alpha 1 will start, it will be possible to post around videos and that will bring tons of new players to the game.
Actually there is no real footage of Fractured and everything is just a bunch of infos on a blog/forum. The majority of players don't want to "lose time" reading so video content will hook them up better and faster.
Having some streamers on Twitch playing Fractured will probably be the best way to fire up a spotlight on the game.
Also getting into Steam (on Greenlight maybe?) will probably be the best way to advertise the game to the largest audience possible.
