The Laser Gun is a default weapon that can be used by players. It requires ammunition in order to be used.
The laser is fired from the gun which moves foreward at a fast speed though it's possible to dodge it. Once a laser hitted an enemy the enemy will receive around 35 damage (?).
Laser ammo can be added to any level in sets of 5.
Like a bomb, lasers can damage enemies in solo or multiplayer mode. If used cleverly, they can also be helpful in player-created puzzles.
