This is either the worst time to get a concussion or, the curious journalist inside of me says, the best. A week before I'm set to fly off to San Francisco for GDC, the annual Game Developers Conference, I lose my footing on a slushy mountain while hiking in NY and slam my head on a rock. I feel the world slow around me as I fall backwards, until my skull bounces off the rock I'd just slipped on and time (and pain) rushes back to me. I make it all the way down the mountain with throbbing temples, a whole lot of whiplash and a fear of rocks -- a minor concussion, fortunately. A concussion is a type of brain injury -- any kind of which can be tricky. It basically means you've rattled and bruised your brain in your head enough that you either pass out, lose memory or, in a less worst case scenario, deal with a terrible, persistent headache coupled with long-lasting sensitivities to light, sound, etc. Depending on how bad a hit you suffered, symptoms can last a few hours or a few months.

Back in 2015, hidden in a tiny soundproof room at CES in Las Vegas, a demo for a cops-versus-giant robot game called Showdown blew me away. At one point, I watched in amazement as fully rendered, three-dimensional bullets whizzed by my virtual face in slow motion. When I took the Oculus Rift off, all I could think was, "this is the experience that will blow people away when it finally reaches the public." Well, that day has come, in the form of another game called Robo Recall -- the best and most polished virtual reality gaming experience I've seen to date. Developed exclusively for the Oculus Rift with the Oculus Touch controllers in mind, the game (developed from an early demo of Bullet Train) is incredibly well designed and sophisticated, but still easy enough to grasp for new VR users.

If you've ever wanted to know what's like to be a robot and mercilessly kill other robots by a variety of means, Robo Recall is available to play for free on Oculus Rift. After an appearance during the Unreal Engine keynote at the Game Developers Conference today, Epic Games released Robo Recall for free, exclusive to the virtual reality system Oculus Rift. The game is set in the not-too-distant future where nearly everyone owns a robot.The only problem is the robots start to go bad, so it's your job as a fellow robot to "recall" the robots through various violent means, including shooting them, bashing them and shooting them some more.

At Oculus Connect 2 last year, Epic Games' Bullet Train demo stole the show -- leaning heavily on the "bullet time" effect popularized by the Matrix films to create a smooth, action-packed shooter that let players take down multiple enemies in slow motion. It had a neat gimmick: it used virtual reality to bend reality in a way we've only seen in the movies. The team brought the concept back to Oculus developer conference again this year as the heavily refined Robo Recall: a frantic, physics-based shooter with a sense of humor. Hands-down, it's one of the best Oculus Touch experiences I saw at the show. When it launches early next year, it will be absolutely free.
