This gun revolutionized squad level support weapon design. The gun fires a caseless cartridge consisting of a block of propellant with a bullet buried inside. The resultant weight and space savings allow it to have a very high magazine capacity.
The H&K G11 is an assault rifle developed during the late 1960s by Heckler & Koch. It has revolutionized assault weapon design and fires 4.7mm caseless, a cartridge consisting of a block of propellant with a bullet buried inside. The loading and feed mechanism is physically very complicated but exceptionally fast and reliable. Rounds are fed into the weapon from a magazine that lies above and parallel with the barrel.
The rounds are oriented vertically (at 90 degrees to the bore) and are fed downwards into the rotary chamber so that they can be rotated 90 degrees for firing. Because the H&K G11 uses caseless ammunition, there are no extraction and ejection steps. The resultant weight and space savings allow the H&K G11 to have a very high magazine of 50-round capacity.
The most powerful assault rifle in the game; after ammo modifiers it is significantly stronger than the next best choice, the H&K P90c. On the other hand, the even stronger Vindicator minigun uses the same ammo, so that may be worth saving up for. Incidentally, the P90c costs 1 AP less to fire.
Snake Morton, one of the Morton brothers, uses this gun. Failing that, it can be purchased in San Francisco. Also, some Hubologists that one can encounter outside of San Francisco also carry this weapon. Killing these Hubologists does not affecg Karma, and will not make the Hubologists in San Francisco turn hostile, even if many are killed. The Enclave soldiers that wear combat armor in Navarro also have these equipped.
Originally, the weapon was supposed to belong to the Big Guns skill and have a bipod.
The real-world counterpart for the G11 is actually a rifle that was developed for the German Bundeswehr but was canceled because of defense budget cuts after the reunification. The E variant is specifically designed for Special Ops., equipped with a low-light scope and a suppressor. Neither of these features are present in the game, which is especially apparent when the G11E is compared to the FN FAL (night sight).
