Resident Evil 2
The sequel to 1996's Resident Evil, Resident Evil 2 features a dramatic change of pace from its predecessor, moving the action from a remote mansion in the wilderness to the heart of zombie-infested Raccoon City.
Like the first game, there are two primary protagonists, but unlike Resident Evil, the order in which you play each character changes certain events in the story (such as when specific weapons are found, or what kills certain characters). The player is given control of Claire Redfield, younger sister of the previous game's protagonist, Chris, and Leon Scott Kennedy, a rookie police officer. The game also marks the first appearances of Ada Wong, who would return as a major character in Resident Evil 4 and Resident Evil 6, and Sherry Birkin, who was one of the main protagonists of Resident Evil 6. The game is also notable for being the only one in the main series not to feature any living members of either S.T.A.R.S. team from the previous game.
Resident Evil 2 also introduces a host of new mechanics not present in the first game, including the ability to modify firearms and fire-selector switches for several weapons. It also features automatic weapons available without first beating the game, and overall has more firearms depicted than the previous title.
Please note that, after the game has been completed once, the player unlocks "Arrange Mode," which changes the placement of several items and weapons across the game. All weapon locations are stated only when Arrange Mode is disabled, as the locations are otherwise completely randomized.
The following weapons were used in the videogame Resident Evil 2:
Heckler & Koch VP70M
The Heckler & Koch VP70M is Leon's primary weapon. It's also in Hunk's inventory in his bonus game. As with the real world handgun, Leon must locate the pistol's stock before the 3-round burst fire is unlocked; he acquires this inside the RPD building about a quarter of the way through his scenario.
This is the very first upgradable weapon in the series, as well as the first to support 3-round burst fire. The damage from each shot remains the same, but the 3-round burst will always knock a zombie down.
Browning Hi-Power Mark III
The Browning Hi-Power is Claire's primary weapon. Claire finds it in a police car glove compartment during the intro FMV. The pistol is also used by Ada Wong during the mini mission where the player controls her. Ada's Browning Hi-Power is held slightly at an angle and is fired faster than Claire's HP Pistol. Annette and William Birkin are also seen using the weapon during the FMV cutscenes.
Interestingly, the in-game description specifically states it's actually an FN Hi-Power, which is the exact same gun, with an FN trademark.
IMI Desert Eagle Mark XIX
Leon finds a nickel-plated Desert Eagle Mark XIX with custom wooden grips with an imbedded gold S.T.A.R.S. emblem in a guard shack next to a dead guard in Scenario "A" or in the S.T.A.R.S. weapon safe in Scenario "B". Later, Leon can find parts in the Underground Facility to enhance the already extremely powerful weapon. The upgrades gives the gun a blued slide and (matching) 10" barrel. However, the increase in firepower significantly increases the recoil and slows down Leon when firing it.
The weapon is chambered in .50 Action Express rounds, technically making it the most powerful handgun in the series until the Smith & Wesson Model 500 appeared six years later in Resident Evil 4. In-game, the weapon holds 8 rounds, despite the fact its real life model can only hold 7. This would only be possible in real life if a round is already chambered before inserting a full magazine (7+1); given how most players opt to reload by using the inventory menu, it's likely Leon locks the slide back on an empty chamber and manually loads in the eighth cartridge. The gun is extremely powerful, but extra ammo is scarce, so it's best reserved for boss fights.
R.P.D. Police Chief Bryan Irons pulls a blued Desert Eagle on Claire twice in the game: when they first meet, and shortly before Claire enters the sewers. Depending on which scenario is being played, he is killed by either William Birkin or a G-Creature halfway through the game. Although he was never depicted as having fired it onscreen, it is heavily implied that he used this gun to kill the Mayor's daughter just as Claire arrived in the area, as well as a police officer named Ed earlier as mentioned in his diary. HUNK also carries the original non-upgraded version of the weapon in his bonus game.
As an interesting side note, this Desert Eagle has become a series staple, appearing in the hands of U.S.S. and ECHO SIX operators in Operation Raccoon City (which takes place concurrent to this and Resident Evil 3), apparently as standard BSAA issue in Resident Evil 5 and Resident Evil Revelations; Leon gets his hands on one again in Resident Evil 6. In all iterations after this, the Desert Eagle is called the Lightning Hawk.
Colt Single Action Army
Claire receives a Colt Single Action Army when she unlocks her second outfit. It is chambered in the standard 9x19mm pistol rounds which is odd for a revolver of this type as it was commonly loaded with .45 Long Colt. Claire fires the SAA from the hip, it has a fast rate of fire do to her fanning the hammer and reloads extremely quickly; which is unusual for the weapon as each shell had to be hand ejected one by one with the ejector rod, instead the weapon acts more like a modern revolver with a swing-out cylinder. Ada carries one in the minigame "Extreme Battle" which was added to most later ports of the game.
In the unlockable bonus game "Extreme Battle", special character Chris Redfield's sidearm is a Beretta 92FS Inox with wood grip panels just like in Resident Evil: Director's Cut. Overall, the handgun plays somewhere between Leon's VP-70M and Claire's Browning Hi Power, but has the added ability to score critical headshots, similar to the Desert Eagle, though these are granted randomly. Holds 15 rounds and for some bizarre reason the weapon's EXAMINE description cuts off in mid sentence.
Heckler & Koch MP5A3
A Raccoon City police officer uses a Heckler & Koch MP5A3 submachine guns on the roof of R.P.D. Headquarters and accidentally shoots down a police helicopter when attacked by zombies in one of the FMV cutscenes. The U.S.S. Squad also use MP5A3 submachine guns during the FMV cutscene encounter with William Birkin. The weapon is not usable during game play. On a side note, the weapons do not appear to have been modeled with an ejection port.
The MAC-11 is first available to the player when they reach the police armory. Both Claire or Leon can take the weapon, but if the weapon is taken by one character in Scenario "A" the other character will not be able to get the weapon in Scenario "B" until very late in the game.
Unlike the other firearms, ammunition is represented in percentage form, with 1% equal to 5 bullets fired; this means that the weapon has a rather astounding capacity of 500 rounds in a standard 32-round magazine. In the "A" Scenario, there is no extra ammo, making it useless after a point (similar to the Calico M110P in Resident Evil: Code Veronica); in the "B" Scenario, it's possible to acquire a spare magazine.
The in-game description says the caliber is .380, signifying that it is in fact a MAC-11. It also features a rather large barrel extension with a perforated shroud around it. In-game, the weapon appears much larger than its real life counterpart, roughly about the same size as a small assault rifle.
Leon first acquires a Remington 870 from the Gunshop from the recently deceased owner, Robert Kendo, only when playing his A scenario. It has a TacStar pistol grip and the barrel has been sawn-off with what's left of a raised vented sight rib on the rest of the barrel. Kendo gets a shot off before the player picks up the weapon giving it 4 rounds, but has a maximum of 5 (Implying it holds 4+1 in the chamber). A second 870 can be found in the S.T.A.R.S. Office in Scenario A and one can be found on the front desk of the Police Station main hall in Scenario B. An upgrade kit is available later in the game which converts it to a Remington 1100, however this would have been impossible in real life as the two models are based on completely different operating systems. Interestingly, when examined, the game specifically states that the gun is a "Remington M1100-P"
Hunk carries this weapon as well in his bonus game.
Remington Model 1100
The Remington Model 1100 can only be obtained by upgrading the Remington 870 using an upgrade kit found later in the game, however this would have been impossible in real life as the two models are based on completely different operating systems. (The Remington 870 is a pump action shotgun while the 1100 is self-loading)
The upgrade kit consists of a full stock, longer barrel, extended tube magazine that adds 2 more rounds, a self loading action (though the time between shots is almost the same, due to Leon being blown back a step from the recoil), and the power is upgraded to the point where it can blow away the upper torso of zombies, rather than just the head.
M79 grenade launcher
Claire obtains a M79 grenade launcher in the S.T.A.R.S. office. The stock is replaced with a wooden pistol grip. The weapon fires an array of fictional rounds, with a choice between Cluster Bomb Burst Rounds, Sulfuric Acid Rounds and Napalm Flame Rounds.
Either Leon or Claire use a FIM-92A Stinger to dispatch the T-103 in their 'B' scenarios. The weapon lacks its IFF box antenna and erroneously functions as a conventional rocket launcher; the FIM-92A is designed for use against aerial targets, not ground targets and cannot fire without a lock-on. That and using it in such close quarters is extremely dangerous on account of the backblast.
A three-barreled Minigun known simply as the "Gatling Gun" is a secret weapon with unlimited ammo that can only be acquired if the player completes the Scenario B game in under 2 1/2 hours without saving and gets a grade of A or B.
Available only for Leon, is a portable chemical flamethrower found in the Underground Research Facility, is used primarily on the Ivy creatures. The flamethrower in-game is based on the M240 flamethrower used in Aliens (sans M16 carry handle).
Only Claire obtains this weapon. The Spark Shot seems to be a large short range stun gun with a higher voltage over normal stun guns.
