The missile launcher was a weapon introduced in TRON: Uprising.
The launcher is large, supported on the shoulder, and fires self-propelled missile-like projectiles. It has a view scope and the chamber must be cocked before firing. Though the missiles can be aimed, their paths are extremely unpredictable, looping wildly before landing in the general vicinity of the target.
This weapon was used by Pavel to shoot at Beck, Mara, Zed, and Hopper as they escaped Argon Square in the Light Roadster.
