Achieving 100% completion in Metroid Prime Remastered requires collecting all Missile Expansions, Energy Tanks, Power Bomb Expansions, and Chozo Artifacts, as well as completing your Log Book by scanning every entry. This often means revisiting every single room multiple times with new abilities. Use the map's item tracker (if available in your version) and consult online resources for specific item locations. Be prepared for extensive backtracking and thorough searching.
