The Box Launcher is a weapon available in the Paradise Lost expansion during Enhanced Mode. It fires flat-colored bouncing boxes that kill characters including the Postal Dude on impact and turns their ragdoll into a missile with the same effect. These human missiles will gib characters upon colliision. The Box Launcher also comes with an alternative firing mode that lets the user control the launched boxes.
It can be found in the former RWS Headquarters and current home of the Wise Wang , in the stairway littered with computer monitors.
This weapon is nearly identical to the Bouncy Block Launcher.
