Like its original counterpart (but is a different weapon), the P99 is Bond's (Daniel Craig) weapon of choice and is given to him at the start of several levels (as Walther PPK was weapon of choice of Bond in the Original GoldenEye 007.) The unsilenced version however is only given to Bond on levels where he is not expected to use stealth and when the guards are already alerted to his presence. It is also the players sidearm in multiplayer mode where it has infinite reloads. The P99 has a 15-bullet magazine, however, the weapon will never run out of ammo. Bond also uses this weapon in 2008 Bond movie with Daniel Craig called Quantum Of Solace. It could well have been based off of that model.
This weapon is based off of the original P99, and is like the weapon in the Wii version of GoldenEye 007.
