LS-66 Sabre Direct Energy Rifle

The LS-66 Sabre Direct Energy Rifle (DER) is a weapon in Deus Ex: Human Revolution.

Characteristics
The LS-66 does not fire a set number of "rounds". Instead, it uses batteries, which have an initial charge of 500, which is about ten seconds of sustained fire. While the weapon does have an overheat gauge like the M404 Heavy rifle, it does not seem to heat up when the fire button is held, a possible bug in the initial PC release.

Jean-Francois Dugas, main designer of Deus Ex: Human Revolution says:

"It's a weapon that allows you to shoot through walls so you just have to shoot, really. Combined with the Smart Vision (augmentation to see through walls) it makes for deadly combo. However, I'm telling you right away, it's a very difficult weapon to get..."

Bugs

 * Using the secondary fire key allows the player to look through the telescopic sight on the weapon, providing minor zoom and centering the laser beam on the screen. On the pc version, however, there is a bug where neither the texture for the scope, nor the crosshair appears.
 * The model for the weapon has the scope mounted on the right-hand side of the barrel, where it would be impossible for a right-handed person (eg. Adam) to use.
