Microsoft is marking the launch of Halo: Combat Evolved Anniversary with HaloLivingMonument.com. Fans are invited to upload moments of their favorite Halo memories from the last decade, which will become part of an interactive, 3D mosaic image of Master Chief.

“Users can explore the content of the mosaic, rate their favorite submissions and share them with friends on Facebook and Twitter. Contributing to the mosaic is as easy as uploading an image from Facebook or leaving a comment about your favorite Halo memory,” says Microsoft. “In addition, fans who add their photos to the interactive memorial can see their contributions immortalized in a personalized, live-action “Halo Tribute” video that honors the dedication and support of the Halo community over the franchise’s ten year history.”
