The G11 has a large 48-round magazine and fires a very quick 3-round burst (1250 rpm inside the burst with a .2 sec delay between bursts). It has the same hip firing spread as SMGs, despite it being an assault rifle. The G11 uses the same iron sights as the Famas and AUG. The G11 is a "Classified" weapon, meaning it is unlocked by buying all other weapons of its type (Assault Rifles).
The reload animation for the G11 varies from other assault rifles in Call of Duty: Black Ops as the gun loads from a horizontal magazine. The G11 is not a traditional cartridge firearm but instead a caseless one; when reloading or equipping the weapon the player charges the weapon by rotating a "bolt".
The G11 is similar to the M16, but has a shorter damage drop off, less damage, and a higher ROF because of the quicker burst (M16 fires at 937.5 rpm inside the burst compared to the G11's 1250 rpm). Both guns require the same amount of bullets to kill in core modes. In Hardcore, the G11 needs 2 bullets to land to get a kill at longer distances, whereas the M16 only needs one. Although not killing with the G11 in Hardcore at those ranges is very unlikely because there is so little recoil, so that even at the most extreme ranges if the first bullet hits, the 2nd is almost guaranteed to as well. The recoil is very different from the M16 , the G11's recoil sprays in a circle, while the M16's goes up. This, coupled with faster firing rate, make it more suited for CQB than a stock M16. The G11 also has significantly larger ammo capacity than other assault rifles with more total ammo than any guns with dual mags (the Galil and MPL being the only exceptions; it ties the MPL's 192, and is only bested by the Galil's 210). With the Variable Zoom Scope the G11 is useful at extreme ranges in Hardcore gamemodes. Both the Variable Zoom and the Low Power Scope are also helpful in Hardcore gamemodes because at close-medium range you only need one bullet to kill, and the idle sway will make the 3-round burst create a tight triangle of bullets rather than putting all 3 in the same spot, increasing the chances of a hit when you normally would have missed.
Since the G11 only has two attachments, both being optics, there's no use for the perk Warlord, freeing up a slot.Sleight of Hand Pro is recommended, as it cuts its comparably long reload time (when completely empty) in half and makes target acquisition faster, which helps when shooting targets at close range, especially with the long ADS time of the G11's scopes. But scout paired with variable zoom could be a burst-fire sniper rifle.
It should also be noted that the Variable Zoom Scope also zooms in faster with Sleight of Hand Pro, since the G11 is not classified as a Sniper Rifle.
Considering it has such a small hip spread, it can be used in tandem with Steady Aim and become a powerful hip fire weapon, taking few bursts at close range to kill. Its large magazine also eliminates the need for constant reloading common to SMGs. These advantages can make it appropriate for close range to medium-long range fire.
All in all, this rifle easily outmatches the M16 in virtually most situations, but due to its lack of attachments it may suffer from difficulties that an M16 with its available attachments would not have a problem with (specifically underbarrels). An example being a grenade launcher to eliminate large groups in buildings or a flamethrower or masterkey to improve close-quarter capability, where a G11 user would have to stick to conventional firing methods the M16 could switch to a more suitable weapon quickly. It is notable, though, that some of the M16's attachments still doesn't beat the G11 in certain areas, such as the Extended Mag attachment. The M16 with Extended Mag has 45 rounds, or 15 bursts, whereas the G11 has by default 48 rounds, one extra burst.
The G11 is available in Kino der Toten, "Five", Ascension, Call of the Dead, and the "Classic Zombies" DLC through the Mystery Box. It comes with a Low Power Scope and has an accurate three round burst. The G11 is good for headshots due to its low recoil and sway; however, it can be troublesome in higher levels and close quarters.
When Pack-a-Punched, the G11's name is changed to the "G115 Generator," which is a reference to Element 115. It also becomes fully automatic and still features the Low Power Scope. Even when firing on full auto, it still retains its low recoil making it more useful in CQB situations despite its extremely high rate of fire. Double Tap Root Beer is strongly inadvisable because ammo will run short within a round.
