Laser (PUNT)

The  is a mechanic present in PUNT and PUNT: Rebirth. It is a device mounted into the walls that emits a non-damaging beam. Laser emitters are usually coupled with a laser reciever that emits an output when activated, usually activating another element in the chamber to open the exit. Lasers can be blocked by cubes of any type, except for the vapor cube in its active state.

Trivia

 * The inclusion of the lasers was most likely inspired by Portal 2
