The store page mentions some campaign-style progression, with you earning fans through skilled play, unlocking larger stadiums and larger audiences, sponsorship deals and all the usual sports-tangential fluff. Run two laps while it's in your team's possession and that ball's worth two points. To win a round, you need to score five points, but you don't have to dunk after just one lap. There's some extra interesting quirks to the rules. Again, the kind of wheeled anarchy that could kill people in reality, but is just family fun in the virtual sphere. Of course if you're planning on just tackling the person who has the ball, there's no rule saying that you have to keep skating in the same direction. As in basketball, the goal is simply to put the ball in the high, wall-mounted hoop, but only after skating a full lap of the arena. While I wish Ubisoft had fully committed and made the official Battle Angel Alita Motorball game that I've always dreamed of playing, this looks like the next best thing, and more kid-friendly.

It'll be free-to-play when it launches, but the pre-alpha demo is open to all on Uplay and runs until June 14th, or you can add it to your account here on the Ubisoft store. High-speed dunks and brutal tackles make it a sport that only lunatics would play in real life, but thanks to the wonders of videogames, we get to hurt people on rollerskates guilt-free. It's an online three-on-three full-contact mutation of Roller Derby, mixed in with a little basketball.

Among their lineup of grim games about gruff men with guns, Ubisoft dropped a little bit of joy during their big E3 show: Roller Champions, available to play now in pre-alpha demo form.
