The Indie Games Winter Uprising is a promotion that will attempt to fight back "against mediocrity and lameness" on the Indie Games channel, which is roughly comprised of 67% fart sound applications.
The promotion will offer new indie developed titles ranging from prices "as low as 80 to 400 Microsoft Points." A total of thirteen titles will be available during the promotion, from developers such as Ska Studios (The Dishwasher: Dead Samurai).
When the latest dashboard update hit the Xbox 360, the Indie Games channel was placed in the specialty shops section behind the Avatar Marketplace. The decision was criticized by some and defended by Microsoft. One week later, the Indie Games channel was returned to its original slot.
According to the developer of one of the promoted titles, Soulcaster 2, the idea for the promotion is to increase sales by getting more traffic to the Indie Games channel, resulting in more revenue for Microsoft in hopes that the company begins to promote that section of the Marketplace.
