Crossway is a room in Chozo Ruins in Metroid Prime. It is a fairly long room, arched and with a half-pipe along most of its length. To reach the doors to Elder Hall Access and Crossway Access South, Samus may use the Boost Ball in the half-pipe. At this far end, there are also three pieces of Chozo Lore to scan, and a Cordite decoration on the wall that can be destroyed with a Super Missile. Doing this reveals a scan point, which reveals a Spider Ball Track and a Bomb Slot when used. Using the Boost Ball again eventually leads to an elevated Missile Expansion.
