Desperados 2: Cooper's Revenge
Note: The games "Desperados: Wanted Dead Or Alive", "Desperados 2: Cooper's Revenge" and "Desperados 3: Helldorado" all use the same weapons. The same 3D models are used in "Desperados 2" and "Desperados 3", which is why I used some "Desperados 3" wallpapers and screenshots.
The following weapons were used in the game "Desperados 2: Cooper's Revenge":
Remington 1858 New Army
The Remington 1858 New Army, converted to fire cartridges, is a primary handgun of "Desperados" games. It is used by most enemies and by John Cooper and Doc McCoy. One accurate shot will always kill an enemy.
Doc's Long Barreled Remington 1858
Doc McCoy uses the modified Remington 1858 New Army with long barrel. It also can be used with an optical sight and stock. Doc fires much slower than Cooper (Doc cocks the hammer with his thumb, while Cooper uses his left hand).
Winchester Model 1873
The Winchester rifle in game look very similar to the Winchester Model 1873. It's using by many enemies and by Sam Williams. In Sam's hand it's not very good weapon: it's weak, have a handgun range of fire and very seldom killing enemy with one hit (even in head!). It's useful only in close range, so it must be done like a shotgun, not a rifle.
Pablo's Sawed-Off Shotgun
Pablo Sanchez is using the unknown sawed-off double barreled shotgun, obviously with one trigger. This gun have good power and enough range.
Kate's W. W. Marston Three-Barrel Derringer
Kate O'Hara uses W. W. Marston Three-Barrel Derringer, patented 1857 and improved 1864. The pistol is very weak and you can kill only one enemy without reloading. But this is a self-defence weapon, using by Kate when her tricks fail.
