Halo was born on the Eastside, and MoPOP marks the franchise's 25th anniversary with a spotlight on more than 20 rare artifacts: Master Chief's armor, Covenant and UNSC weaponry, original artwork and a few familiar faces, including Atriox. A section salutes the fans who've kept the universe alive through cosplay, art and collectibles. Halo has sold more than 80 million copies since Combat Evolved launched with the original Xbox in 2001, so expect a mix of lifelong players and their curious kids. The spotlight is compact, so pair it with the rest of the museum.
