Lvl 44
You have to get to level 44 and then pay the $2000 to unlock it
Level 44
You G11 is the classified assault rifle meaning you will need to purchase all the assault rifles before it to unlock it. The highest assault rifle before the G11 is the Commando which is unlocked at level 44. So basically the minimum level to unlock it is 44.
The AK-47 is unlocked at level 38 , and it costs 2000 cod points.
Weapon level 5
You unlock it at level 42 and I suggest getting akimbo with it.
In Black Ops multiplayer you unlock the AK-47 at level 38.
As soon as you start the game you get weapons. At level 99 you get the bonus weapon. You unlock other weapons at level 32 also.
The maximum level you can enhance your weapon to in AQWorlds is currently 35 I think. (You have to unlock the higher enhancings by leveling up.)
You unlock gold camo in black ops, when you reach prestige level 14, level 25.
When you reach level 99 on Mafia Wars you can unlock more inventory items and you get the weapon titled "Bonus Weapon".
You shot the futher side of the barrel, and the barrel will move.
