The legacy of the most technologically-advanced species in the Halo games, the Forerunners, can be seen in everywhere you turn. For the first time, Halo: Anniversary Series 2 brings a pair of these ancient machines to your collection: 343 Guilty Spark and a Sentinel. The Sentinel is 'action figure' sized and features articulated appendages, while the Guilty Spark features a reversible eye that can be changed from blue to red. Figures include a base and poles so they can hover near your figures, along with the right wing piece of the UNSC Logo.
