Linebacker G-87 MSGL

The Linebacker G-87 MSGL (Multiple Shot Grenade Launcher) is a weapon in Deus Ex: Human Revolution.

Background
The Linebacker G-87 MSGL is a semi-automatic bullpup grenade launcher developed by Steiner Bisley. It fires low velocity 40mm grenades, each of which are loaded with a high explosive fragmentation charge. The weapon uses a unique horizontally-mounted loading system. The magazine is mounted above the barrel.

Characteristics
The grenades are pushed forward by spring pressure and arrive at the end of the magazine, then are fed as a single row into a spiral feed ramp and rotated 90 degrees, aligning with the chamber. The magazine can hold 6 grenades despite the fact that it seems to carry more than 6 rounds. It is a very powerful weapon that can clear a room full of enemies in seconds. In the bossfight against Jaron Namir the grenade launcher needs only 4 or 5 hits to take him down. As he does not move much after the first hit, this weapon turns the fight into a slaughter.

Behind the scenes

 * The Linebacker G-87 is essentially a bulked-up FN P90, with the same grip layout, magazine, barrel location and so on. Strangely, it seems to have inherited part of the early Heavy rifle design, with the structure resembling an iron sight being formerly mounted on the Kaiga M404 ahead of the front grip.
