Soviet AK-47
The AK-47 is a powerful yet not exactly the most acurate gun. Zoom equiped. Shot to kill ratio 3:1
Assault Rifle (M16 A2 Combat Rifle)
The Assualt Rifle is very high power gun. It can go through more than 1 object at once (boxes, people. 2x ability without cheats. Zoom equiped. Shot to kill ratio 2:1
D5K Destuche (MP5)
The D5K is slightly more powerful then the AK, and twice as accurate. 2x ability Shot to kill ratio 3:1
RC-P90 (FM P90)
An extremely automatic, extremely deadly, waste your ammo kinda gun. With an 80 round clip, reloading isn't a problem. Check on your ammo before going crazy though. 2x ability Shot to kill ratio. Doesn't matter, just let it rip.
Phantom
Only comes in one level and not in multiplayer. This makes me want to smack the games producer. Oh well. 50 round clip and extremely accurate. 2x ability Shot to kill ratio 3:1
Rocket Launcher (M735 Anti-Tank Missile Launcher)
What more can you say? Shot to kill ratio 1:1+
PP7 / PP7 Silenced (PPK)
The PP7 is one of the best guns for it's size. Small and silent, it's very useful on undercover missions. Shot to kill ratio 2:1 It's more accurate then automatics.
Tank
Slow as hell, impossible to aim with, and unprctical, but it still rocks. Shot to kill ratio 1:1
ZMG 9mm (Uzi 9mm)
These guns are cool, but only as doubles. Most of the levels you get this gun in have a better gun anyway, but it's all according to preference. 2x ability. Shot to kill ratio 3:1
Shotgun
Very cool gun, but only in your posession. Non-the-less, accuracy isn't a problem because it fires 5 shots at a time. Shot to kill ratio 1:1
The watch laser is the coolest, even thought it has a short range. Ites very powerful for it's size though. The Moonraker laser however doesn't require ammo, and that's always a plus. 2x ability. Shot to kill ratio watch 1:1 Moonraker 2:1
Grenade Launcher(s)
Grenade Launchers, are very good for artilery assault. It's firing rate is very rapid for an explosive weapon. 2x ability. Shot to kill ratio 1:1+
Grenades
Grenades take a good distance aim. Since they don't stick to the ground like mines, they are hard to use, but useful in a pinch. Shot to kill ratio 1:1+
Remote mines
Remote Mines are very useful, but a damn glitch in the game allows only 8 to blow up with the detonator. Shot to kill ratio 1:1+
Proximity mines
Proximity mines, ar my personal favorite weapon. Kills multiple guys with a single mine, and alerts you to where guys are coming from. If only it didn't blow you up too, it would be the perfect weapon. Shot to kill ratio 1:1+
Timed mines
Timed mines are like grendes that don't roll. Very useful in some cases. Escape for instance. Shot to kill ratio 1:1+
