Xbox Live's Summer of Arcade will have treats for Minecraft and Trials players--even if they don't purchase a single game during Microsoft's promo. Starting July 18th, free content is coming to both popular XBLA games.

Minecraft players will be able to download a free skin pack, featuring one skin for each game featured in the ongoing promotion. (Is that a pixelated Tony Hawk we see?)

To access the content, you'll have to visit the "Summer of Arcade experience" on the Xbox Live dashboard.

Trials Evolution players will get five weeks of new content as well. Every week, a new track will be made available, inspired by that week's Arcade release. This year's lineup includes Tony Hawk's Pro Skater HD, Wreckateer, Deadlight, Hybrid, and Dust: An Elysian Tail.
