Laser Sight

The Laser sight will appear in Left 4 Dead 2 as a tool used to enhance the targeting on all weapons. The laser is the concept of the LLM01 laser sight. The laser can be attached to any weapon of choice(except for pistols/magnum). Survivors have been seen picking up the laser sight in beta footage of Dark Carnival, on the first level. While using the laser sight, you will have better accuracy.

The laser sight cannot be transferred to other weapons or the exact same weapon once the player changes their gun. An example is having a laser sight-equipped to an auto shotgun and picking up another auto shotgun; the new auto shotgun will not have a laser sight.

 * This video features a laser sight gameplay, which confirms that it increases your weapon's accuracy when equipped.
 * While having the laser equipped, it is possible to use your flashlight as seen in the video above.

Behind the Scenes
The laser sight was originally an upgrade in Left 4 Dead, but was unused in the final version. However, mods on the PC version allow the player to use upgrades, which lets players use the laser sight in Left 4 Dead.
