After accruing millions of fans and billions of dollars through mainstream blockbusters such as the Call of Duty franchise, Activision is going indie. Dark Reign: Redux is a modern, fan-made remake of the 1997 title, Dark Reign: The Future of War, which was developed by Auran and published by Activision. The revamp is available on XBLIG and was developed by Magnetar (no, that's not a Pokemon) Games to include updated resolution, widescreen, and PC, console and mobile capability.
Dark Reign: Redux is $5 (400 MS Points) on XBLIG now, and buying it supports the indie and mega-huge gaming industry in one blow.
Update: Activision isn't the direct publisher of Dark Reign: Redux, but it did OK the title in a licensing agreement with Magnetar Games, who self-published it.
