Return to Castle Wolfenstein
The following weapons can be seen in the video game Return to Castle Wolfenstein:
The first gun available in the game is a Luger P08 pistol. Despite having an unthreaded barrel, it can later fit a screw-on suppressor; in a rather odd model glitch, the animation for this being attached has the toggle lock lag slightly behind the rest of the gun model, making it look like it is shaking from side to side.
The Colt M1911A1 first appears in the mission prior to the V2 sabotage, dropped by parachute in a small island across a lake, along with .45 caliber ammunition, which will come in handy for the player when they get the Thompson as they pick up the M1911 in the same level. In one level BJ is given a pair of M1911A1 pistols to use, and can dual-wield them. Unusually, they are both reloaded entirely on-screen, rather than just releasing the magazines on-screen and then dropping them out of sight to avoid this as many games do.
Note: All submachine guns present in the game are in reality open-bolt weapons, but are modeled and animated as if they are closed-bolt.
The most common weapon used by German soldiers, as usual in fictional WW2 settings, and is the third weapon BJ can pick up. Ammunition for the MP40 is extremely common throughout most of the game.
The Sten Mk IIS is a silenced weapon using the same ammunition as the MP40, and must be fired in bursts to prevent it overheating; if it overheats, there is a brief pause when it can't fire and steam (?) escapes from the barrel shroud. On another note, the Elite Guards use this gun as their standard weapon, which seems strange for the normal player, but those could be "Gerät Potsdam" weapons, identical bootleg copies of the Sten manufactured in Germany for infiltration and sabotage acts. The weapon icon is a conventional un-suppressed Sten Mk II, and the model for the gun features a perforated heat-shield part way down the suppressor much like the one found on the Mk II.
BJ is given a M1A1 Thompson submachine gun by a local Resistance member in a village. The .45 ACP ammo for it is unfortunately extremely rare. However, this is balanced out by making it the most powerful submachine gun of the game, unable to overheat, but boasting about the same power as the Sten. It feeds from 30-round magazines, rather than the other SMGs using 32-round mags.
Rifles & Carbines
The first long-ranged weapon BJ acquires is a Karabiner 98k. Later in the game a scope can be found for it to make it even more effective; it is sometimes seen in the hands of enemies, but is nothing like as common as the MP40. Oddly it is depicted with a 10 round en-bloc clip; there is some evidence that it was originally intended to be an M1 Garand. There is no visible bolt-operating animation and the weapon appears to be semi-automatic with only a sound effect of a bolt action playing, but if the field of view settings are altered it can be seen that BJ's normally off-screen hand actually does operate the action after each shot.
Used by German paratroops and as per videogame norms is a supergun; the FG 42 Ausf. G (late-war model) combines the power of a rifle with reasonably fast fire [automatic, but at semi-auto speed] and a scope. In the late game it is more or less the default weapon BJ will be using.
The M3 Carbine is presented in the game as an OSA-modified weapon called the "Snooper Rifle" fitted with a suppressor (the barrel is the same shape as the normal M3, however, only mounting an anachronistic Korean War-era T23 conical flash hider) and using special ammunition. It uses the early M1 / M2 scope with the IR lamp mounted underneath the weapon (though it lacks the correct vertical front grip), and, surprisingly, is depicted with a realistic black-and-white image rather than the normal red or green tint seen in movies and video games. Ammunition for this weapon is extremely rare, and hardly ever seen. The M3 was first used in the invasion of Okinawa in 1945, two years after the setting of this game.
Winchester Model 1912
The Winchester Model 1912 appears as "Shotgun" in the Xbox version of the game, called "Tides of War". It is modeled with an unrealistically long forend.
In several levels mounted MG42 machine guns are present. Like in Medal of Honor: Allied Assault, the rate of fire and distinct report are nowhere near accurate. They have unlimited ammunition and feed from an invisible ammo source, and can be destroyed with explosives to prevent enemies from using them.
The MG34 machine gun is seen in the hull mount of the Panzer tank during Chapter 4.
Around halfway through the game, BJ acquires a prototype of a fictional portable belt-fed gatling gun called the "Venom." The readable tech manual picked up in the game as a mission objective says it uses 7.92mm saboted light armour piercing rounds. However, this is at odds with the 12.7mm (.50 cal) ammunition the gun uses in game. Like the Sten, it can overheat when fired for longer periods of time, but thanks to the gatling-type design it takes longer (about 100-150 rounds in Multiplayer, 150-200 in Singleplayer) to do so.
The M2 Flamethrower is used by German troops after Chapter 3. It is a powerful CQC weapon, but finding "ammo" for it can be a problem. The M2 is devastating, dealing fire damage over time, and turning human enemies into ashes in no time. In MP, it is used by both factions.
Panzerfausts are the game's version of a rocket launcher; as usual, these are incorrectly depicted as launching rocket-assisted projectiles rather than being recoilless rifles.
Model 24 Stielhandgranate
The Model 24 Stielhandgranate appears as the default hand grenade in the game. It is used by Axis forces in the MP part of the game.
Mk 2 Hand Grenade
The Mk 2 hand grenade is first introduced in Chapter 4. Performs as the Model 24; BJ will use up all of the Mk 2s he is carrying before he starts using Stielhandgrantes. In multiplayer, it is used by the Allies.
M18 Smoke Grenade
The M18 smoke grenade is used by both Allied and Axis forces in the multiplayer part of the game. It is used to mark the position of a devastating airstrike, killing anything in its way. Only Lieutenants can use the M18 smoke grenade.
A Flakvierling 38 AA gun can be seen on one multiplayer map.
