Controlled/Uncontrolled teleport launches occur when a player uses CPG (Cube Placement Glitch) and performs a controlled/uncontrolled teleport while conserving the speed of the teleport by jumping at the perfect time, resulting in extraordinary amounts of speed. The video below showcases all known useful controlled/uncontrolled teleport launches that save time over a run that does not utilize launches at all.

Exception: The 1-4 outdated launches are not teleport launches but are unique controlled teleports that bounce a player from a wall. A jump is executed to conserve speed, but not in a way that results in teleport launches.
