Mojang's best known for the indie blockbuster Minecraft, but today heralds the launch of the open beta for its new game, Scrolls. It's been a long time coming, and the title itself was the focus of a courtroom squabble, as much as Notch would've liked to hash out the early roadblock in a rocket-filled arena. While it's admittedly not "feature complete," you can test your card-battling skills in casual and ranked online match-ups. The card trading forum is up and running, as is the in-game store for bolstering your deck using gold earned through triumph, and "shards" purchased with real dough. You can tweak your deck using the builder and 25 trials are available off the bat to school you in strategy. Access to the open beta will cost you $20, £13 or 15 euros, but really, you're buying the full game early, as all future updates will be free to beta adopters. The purchase page isn't live just yet, but it'll be available to download for PC and Mac at some point today. Hit the source link to brush up on the mechanics if you can't wait to attack the trials, or check out the trailer below for a quick fix.
