Microsoft has officially announced the first micro-transaction based free-to-play game will release for the Xbox 360. Multiplayer combat game Happy Wars will be a game free for all Xbox Live Gold members and will feature items available for purchase to customize your character’s appearance.

Ascend: New Gods is another free-to-play title planned for 2013 that will also use the micro-transaction business model. There have been free game releases on Xbox Live before, but most of them have been sponsored or advertising based, such as Doritos Crash Course or 1 vs. 100.
