The Weaponry in AQ2 is very realistic and each weapon is based on real life guns. No more rocket launchers and laser blasters. In teamplay you get one extra clip to go with your pistol and unique weapon. In deathmatch you get just the 12 bullets in your gun but you can obtain more ammo from the level.

The SOG 37 Combat Knife

Everyone has a knife with him and with good reason. The knife can slice your enemy dead in seconds or if you prefer killing from a distance, you can throw the knife. A thrown knife inflicts the same amount of damage as the sniper rifle. You can pick up knives from dead bodies or choose knives as your unique weapons thus having 10 instead of one.

The Heckler & Kock MK23

The pistol is your basic weapon. But don't let that fact fool you, it's accurate, reliable and powerful. One shot does more damage than a shot from the MP5. The pistol is great for finishing wounded targets off but at longer ranges it loses efficiency. And if you find another pistol, you can use two pistols at the same time. The akimbo pistols can also be chosen as the unique weapon. The pistol holds 12 bullets and has two firing modes, automatic and semi-automatic.

The Handcannon

The sawed-off shotgun makes the perfect close range weapon.
Anyone in a 3 meter radius gets his ass blown off. But at longer ranges, it'll only piss your enemy off so better sneak up close. The handcannon holds two shells and shoots both of them simultaneously. You'll have 12 extra shells in teamplay. Best used with the slippers in a map like kumanru.

The Heckler & Koch Beneli Super 90 M3

The M3 Shotgun is a good all-round weapon. It's deadly in close, medium and maybe a bit strangely, it's somewhat effective in longe range too. The rate of fire isn't fast but on clean shot can kill your foe. The shotgun holds 7 shells and they must be realoded one at a time. A Shellbox also contains 7 shells. 

The Heckler & Koch MP5

The MP5 is a fast firing sub-machine gun. You can slay down enemies with haste as it is also quite accurate but you wont hit anything while running. A hit from the MP5 does less damage than the pistol or the M4. The MP5 holds 30 bullets but they can run out really fast. Very deadly with the laser sight. Can be used as full automatic or 3-bullet burst.

The M4 Colt

The M4 assault rifle is much more powerful than the MP5 and more inaccurate too. The fact that the muzzle tends to lean up doesn't help either. But the brute force and efficiency in longe range comat makes the M4 a formidable weapon. It holds 24 bullets and they run out even faster than on the MP5. Can be used as full automatic or 3-bullet burst.
 

The SIG Sauer SSG 3000

The sniper rifle isn't easy to master but when used properly, it's by far the deadliest weapon available. Though meant for long range, it can well be used in close combat. Hipshots are inaccurate no matter how you shoot but when the scope is used, it always hits what you're aiming at. Every shot except a legshot leads to imminent death. The scope is equipped with 2x, 4x and 6x zoom. The rifle can hold 6 bullets and  they must be loaded one at a time. The ammoboxes however hold 10 bullets. This probably my favorite weapon.

The M26 Fragmentation Grenade

The grenade is a real room cleaner. It has a large blast radius and inflicts leathal damage although you can halve it's effects by crouching. The grenade has three throwing distances: short, medium and long. The grenade is available only in deathmatch and you can carry two at a time.

The Equipment

These items help you to survive but some work only with specific weapons.

The Kevlar Vest

The kevlar gives you protection from chest shots and bullets can't penetrate it. But you still receive a little damage from impact caused by the bullet. Against the  shotgun, handcannon and knife the kevlar is of no use. The sniper rifle does go through the vest but you won't die, just get badly hurt. 

The Silencer

The silencer is an assasin's best friend. The pistol, MP5 and sniper rifle will make almost no sound at all and the muzzle flash is gone.

The Laser Sight

The laser sight can be attached to the pistol, MP5 and M4. It makes aiming always as accurate as can be, even if you are running and jumping. Very deadly if used correctly.

The Stealth Slippers

Now you can move silently. Your movement won't make any sound at all. Great for sneaking up on people with a handcannon or knives.

The Bandolier

With the bandolier you can carry twice the ammo. In teamplay you'll start with two extra clips and in deathmatch even more is available.
