This is the infamous Laser guided rocket launcher from Half-Life 2, it took me alot of time to recreate it in Teardown.
Before you enable the mod go into Mods Options menu, it can be found under enable button in mod list.
Controls
LMB - Shoot rockets
RMB - Switch Laser on/off (Switching laser turns the rocket into a "normal" one, you can change between modes during flight, good for doing trickshots or getting into tight places)
Requires: Ability to read
