Microsoft has just launched Halo Living Monument - a user-generated site that ask users to upload pictures of their favourite Halo memories from the last 10 years to create an "interactive 3D mosaic".
You can upload your images now, rate other submissions and share them over Facebook and Twitter.
On top of that, there's a new live action trailer, as seen below, to offer a bit of context.
Halo Combat Evolved Anniversary arrives in stores tomorrow.
"It's an awkward reinvention that manages to be at once faithful and a little wide of the mark," read Eurogamer's 8/10 Halo Anniversary review. "But such is the strength of Combat Evolved, this is still an Anniversary that's worth celebrating."
