A brand-new teaser for Halo Infinite has arrived amid ongoing rumors that the game's multiplayer element will be released early to celebrate the franchise's 20th anniversary. The new teaser shows off the backstory of how Master Chief got his exoskeleton technology.

"After the bombardment of a UNSC excavation site, colonial miners volunteered to extract an ore critical to the Master Chief's exoskeleton despite threat of the cave collapsing," reads a line from the video.

This is the third episode in the UNSC Archives series that digs into the "untold stories of humanity and heroism" from the Halo lore. The first revealed the heartbreaking story behind Master Chief's energy shields and the second revealed the origins of Master Chief's new Grappleshot for Halo Infinite.
