Remember Reach was a Microsoft marketing campaign for Halo: Reach. The campaign was centered around the website, www.rememberreach.com, where users could create a "light monument" of Noble Team composed of thousands of points of light and generated by a real robotic arm. The monument was constructed by special camera equipment which captured and composited the movements and light pulses from the robotic arm, which visitors could see in action on the website. Each user was able to designate a single point of light for the robotic arm, adding their contribution to the light sculpture. The sculpture was completed on September 14, 2010.
In addition, the campaign will feature several live-action shorts by the director Noam Murro, who also directed the Birth of a Spartan teaser. The videos will show glimpses of what life was like before the Covenant invasion of Reach. The first video in the campaign, Patrol, was first shown on August 17, 2010 during GamesCom 2010. The promotional site was also launched in the same day, and was opened fully on August 23, 2010. The second film, Deliver Hope, was released on August 26.
