The Momentum Reflector Gun is a subclass of the LinkGun adapted to boosting yourself from the ground and walls rather than killing your opponents! The gun is designed for the usage in Trial maps, which may and should challenge you to climb upon walls by aiming downards with this gun.
Beware! This gun is for advanced trial players! Boosting yourself up requires very precious aiming skills!
This is a gimmick for Level Designers to design more complicated puzzles.
