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 a 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 inital 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..."

Combat Statistics

 * Damage / Round: 7 (upgradable to 10)
 * Rate of Fire: 10
 * DPX: 70 (upgradable to 100)
 * The Laser Rifle has the highest DPX in the game. When fully upgraded, no other hand-held weapon can kill a single target faster.  It is basically an improved Heavy Rifle in that it has a higher DPX AND much smaller ammo containers (2x1 instead of 3x2).  This is counterbalanced by the relatively late point in the game when you can first acquire this weapon, and that it's ammo is rare and not sold by merchants.  It's a boss-killer.  Using it on anything else would be a waste of its power and ammo.
