The following weapons were used in the video game Perfect Dark:
PLEASE NOTE: Only firearms based on real firearms will be shown here. There is no point to having alien or fictional weaponry.
Colt Double Eagle
The Colt Double Eagle appears as the Falcon 2. It is the workhorse handgun of the Carrington Institute, available with a suppressor or a scope, but not both at the same time. The Falcon 2 is almost always given to the player at the start of a mission, in one of the 3 flavors (suppressed, scoped, vanilla). Each flavor comes with a laser aiming module (LAM) attached to the front of the trigger guard.
Beretta 93R 'Auto-9'
The Mag Sec 4 is a large handgun based off of the modified Beretta 93R 'Auto-9' from RoboCop (and many later films) in function. It is carried by security personnel at Area 51. The Mag Sec 4 is able to fire single shots or 3 round bursts from a 9 round magazine. It is noticeably inaccurate, even at short range. In appearance, it has been given some futuristic contours, that don't really disguise the design beneath.
The DY 357 Magnum, based on a stainless Colt Python, is a revolver carried by FBI agents and G5 building guards in the Chicago level. It can only be fired in double action, and there is a fairly long delay between pulling the trigger and the gun actually firing. Trent Easton, the NSA director turned Skedar pawn, carries a custom gold 357 called the "DY 357 LX." It is described as being loaded with frangible bullets that cause an instant kill.
The CMP (combat machine pistol) 150 is a SMG with the secondary function to track targets. Passing the reticule over a target marks them, and the weapon auto tracks them in the order that they were tagged. The CMP is carried by all the rank and file of dataDyne, and local unit commanders seem to enjoy the unique privilege to carry two. The CMP 150 is based on a Steyr TMP, except that the shells eject to the left.
The AR 34 is the Carrington Institute assault rifle, and is pretty much just a really wide FAMAS. Carried usually only by CI guards, at one point in development Joanna was going to get one for nearly every mission. That would have made the game too easy (too fun) so it was decided against. As stated by the game, the bullpup design makes it quite accurate. In easily the most enjoyable scene in the game, Joanna uses an AR 34 to provide covering fire for an escaping friendly dropship and fend off an attack of alien warriors, all in her best party dress.
Walther WA 2000
The Sniper Rifle in the game is a Walther WA 2000 with a futuristic Scope, it incorrectly holds 8 rounds. It is used by Joanna to rescue the ambassador on Carrington Villia: Hostage One on the Agent and Special Agent Difficulties.
The basic weapons from Goldeneye 007 are unlockable in Perfect Dark through qualifying at the shooting range. They have had their names changed for legal reasons (one must assume) and their appearances slightly changed to fit Perfect Dark's style.
The CC13 is the new name for the DD44 Dostovei, based on the Tokarev TT-33.
SA Vz.61 Skorpion
The newly leet-speaked "KLO 1313" (named after Ken Lobb, a Rareware employee), is based on the Skorpion sub-machine gun. As in Goldeneye, it can be dual-wielded, though this does little to make up for it's inaccuracy and next to harmless bullets.
The old ZMG 9mm has been renamed the ZZT 9mm. It is modeled after a Micro Uzi, though has been scaled up to look big and impressive.
Heckler & Koch MP5K
The MP5K appears in the game as the DMC, originally called the D5K Deutsche in Goldeneye. It can be dual wielded.
The FN P90 appears in the game as the RCP-45. Despite the similar name and function to the RCP 120, it is not the same weapon at all. In Goldeneye it was called the RCP-90, but it has not lost 1/2 of it's power, fear not.
Norinco Type 56-1
The Norinco Type 56-1 appears in the game as the KF-7 Special, called the KF-7 Soviet in Goldeneye. It has the folding stock removed.
Still looks like a pencil in first-person view.
The M16A1 appears in the game as the AR53. The AR53, previously called the AR33, has no stock in first-person view (despite having one on it's world model) and is also held with only one hand(!), just like in Goldeneye.
