Minecraft and Trials Evolution will receive "exclusive content" on the Xbox 360, to celebrate five years of Microsoft's Summer of Arcade promotion. Beginning July 18, Minecraft players can nab a "customized Summer of Arcade skin pack" with skins inspired by this year's five Summer games. At the same time Trials Evolution will get a new themed track, once a week, alongside each new game.For the Minecraft promo, players can download the skins by visiting the "Summer of Arcade experience" ad on the Xbox Live dashboard.The Summer of Arcade kicks off next week with Tony Hawk's Pro Skater HD. A safe bet is that the special Trials map derived from that game includes 900 laps of something.
