Hi-Rez Studios announced during PAX East that it plans to revive the Tribes franchise with Tribes: Ascend, a multiplayer shooter that will launch in late 2011. This game will pave the way for Tribes Universe, a persistent world MMOFPS that can handle large-scale combat. 

To draw fans to the game's Facebook page, Hi-Rez has been releasing pieces of Tribes: Ascend concept art when various fan milestones are reached. Four pieces of art have been posted so far that feature the light and medium Blood Eagle and Diamond Sword. You can check them out after the jump.
