A toy projectile launcher for launching projectiles, e.g, toy foam darts, from a hopper. One or more agitating members inside the hopper to enable the projectiles to drop into a firing chamber under the hopper. A hopper cover has a collapsible ceiling with nested members and a ceiling plate to maintain the projectiles toward the bottom of the hopper. A catch coupled to the ceiling plate engages an opening in a hopper wall to prevent the ceiling from collapsing when the hopper cover is closed. Where there are multiple vertically spaced-apart openings in the hopper wall, the catch may disengage from a first opening, and then engage a lower, second opening in the hopper wall, as the number of projectiles in the hopper drops and the ceiling plate descends in the hopper. A rotating track and a push rod advance projectiles from the firing chamber to flywheels for launch.
