Weapon Upgrades & Customization — Resident Evil 3: Nemesis Guide

Weapon Upgrades & Customization

Maximizing your firepower in Resident Evil 3: Nemesis is absolutely crucial for survival against the relentless Nemesis and the hordes of infected. Unlike some other entries in the series, weapon customization here involves finding specific "Weapon Parts" that can be combined with their corresponding base weapons to significantly enhance their capabilities. These upgrades are permanent once applied, so generally, the sooner you acquire and apply them, the longer you benefit from their increased potency.

weapon part locations can sometimes vary slightly depending on the specific version of Resident Evil 3: Nemesis you are playing (PC, PlayStation, GameCube, Dreamcast) and, more significantly, on the choices you make during "Live Selections" or the character you are playing as (Jill or Carlos). This guide focuses primarily on the original PlayStation version's most common paths, but will highlight known variations where applicable. Always double-check your surroundings!

Weapon Part Acquisition & Combination

To upgrade a weapon, you must first find its corresponding "Weapon Part." Once you have both the base weapon and its specific part in your inventory, open your inventory screen, select the Weapon Part, and choose "Combine" with the appropriate weapon. The upgrade is instantaneous and permanent.

Here's a breakdown of the upgradeable weapons and their elusive parts:

Shotgun (Benelli M3S) Upgrades: Assault Shotgun

The Shotgun is a powerful close-range weapon, and its upgrade significantly improves its effectiveness against groups of enemies and larger threats by increasing its firing rate and spread.

• Base Weapon Location: The Shotgun is found early in the game.
  • Jill: Inside the Gun Shop Kendo, located in Uptown. After the initial Nemesis encounter, head towards the main street and enter the shop. It's on the counter.
  • Carlos: Carlos starts with an M4A1 Assault Rifle, but can pick up a Shotgun later if needed.
• Shotgun Part A Location: This crucial component is found within the Raccoon City Police Department (RPD).
  • Jill: After gaining access to the RPD, make your way to the S.T.A.R.S. Office on the second floor. Shotgun Part A is located on the desk in the back of the office, near the filing cabinets. This is a common location across most versions.
  • Common Pitfall: Do NOT confuse this with the M4A1 Assault Rifle Carlos finds in Gun Shop Kendo. Shotgun Part A is specifically in the RPD S.T.A.R.S. Office for Jill.
• Shotgun Part B Location: This part is located later in the game, within the Clock Tower.
  • Jill: Once you've navigated through the main hall and solved some of its puzzles, you'll eventually reach the Bell Room / Clock Mechanism Room. Shotgun Part B is usually found on a table or pedestal within this area, often near the large clock mechanism itself.
  • Strategy Tip: This area is often patrolled by Drain Deimos or other creatures. Be prepared for combat.
• Upgrade Result: Assault Shotgun

  Combining Shotgun Part A and Shotgun Part B with the Shotgun creates the Assault Shotgun. This upgraded version boasts a significantly faster firing rate and a wider spread, making it incredibly effective for crowd control against zombies and even dealing substantial damage to larger creatures like Hunters or Nemesis at close range.

Magnum Upgrades: Enhanced Magnum

The Magnum is a devastating weapon, reserved for the toughest enemies and bosses. Its upgrade makes it even more formidable by increasing its damage output and potentially magazine capacity.

• Base Weapon Location: The Magnum is typically acquired in the RPD.
  • Jill: After solving the Blue Gem puzzle in the RPD, the Magnum can be retrieved from the Armory (the room with the weapon lockers). This usually requires the S.T.A.R.S. Card.
  • Common Pitfall: The Magnum is NOT found on Wesker's desk in the S.T.A.R.S. Office. That's a common misconception from other RE titles.
• Magnum Part A Location: This part is found much later in the game, often in the Clock Tower or Hospital section.
  • Jill: In the Clock Tower, after defeating Nemesis for the second time (the battle outside the Clock Tower), you will gain access to the Chapel / Altar Room. Magnum Part A is often found on the altar or a nearby pew.
  • Alternative/Variation (Dreamcast/PC): Some versions might place it in a different part of the Clock Tower or even the Hospital depending on specific Live Selection choices. Always check thoroughly.
• Magnum Part B Location: You'll find Magnum Part B in the Hospital.
  • Jill: Progress through the hospital until you reach the Operating Room (often accessible after restoring power or finding a keycard). Search the room thoroughly; the part is typically on a gurney, a medical cart, or a counter.
  • Strategy Tip: The Hospital is full of Hunters and other dangerous creatures. Ensure you have sufficient healing items and powerful weapons before attempting to retrieve this part.
• Upgrade Result: Enhanced Magnum

  Combining Magnum Part A and Magnum Part B with the Magnum creates the Enhanced Magnum. This upgraded version features increased damage output, making it even more effective against Nemesis, Grave Digger, and other high-health enemies. It can also slightly increase the magazine capacity, reducing the need for reloads during critical boss fights.

Grenade Launcher Upgrades: Enhanced Grenade Launcher

The Grenade Launcher is incredibly versatile, offering various ammunition types (Grenade, Flame, Acid, Freeze) for different situations. Its upgrade primarily enhances its firing speed and reload time.

• Base Weapon Location: The Grenade Launcher is typically found early to mid-game.
  • Jill: In City Hall, after solving the water puzzle to extinguish the fire. It's often found on a table or display case within the main hall or an adjacent office.
  • Carlos: Carlos does not typically acquire the Grenade Launcher.
• Grenade Launcher Part A Location: This part is found in the Clock Tower.
  • Jill: After gaining access to the Clock Tower, explore the various rooms. Grenade Launcher Part A is often found in the Library or a similar study room within the Clock Tower, usually on a bookshelf or a table.
  • Common Pitfall: The Grenade Launcher parts are NOT found in the Hospital Doctor's Lounge. That's a common inaccuracy.
• Grenade Launcher Part B Location: The second part for the Grenade Launcher is also found in the Clock Tower.
  • Jill: This part is typically located in the Chapel / Altar Room of the Clock Tower, often near the altar or on a pew, similar to where Magnum Part A might be found in some versions.
  • Strategy Tip: The Clock Tower is a major hub of activity and Nemesis encounters. Be prepared for multiple confrontations while searching for these parts.
• Upgrade Result: Enhanced Grenade Launcher

  Combining Grenade Launcher Part A and Grenade Launcher Part B with the Grenade Launcher creates the Enhanced Grenade Launcher. This upgrade primarily increases the weapon's firing speed and reduces its reload time, allowing for more rapid deployment of explosive rounds against multiple targets or resilient enemies. This is particularly useful when cycling through different ammo types to exploit enemy weaknesses.

Other Notable Weapons & Customization

While not all weapons have "parts" in the traditional sense, some unique weapons function as direct upgrades or offer specialized utility, fitting the "customization" theme.

• M4A1 Assault Rifle (Carlos's Standard Weapon):
  • Location: Carlos starts with this weapon. Jill can acquire it later in the game if Carlos leaves it behind or if specific Live Selection choices are made. It's often found in the Gun Shop Kendo if Carlos visits it, or later in the Hospital.
  • Customization: The M4A1 has a unique feature. It can be set to either Auto-Fire or Burst-Fire mode.
    • Auto-Fire: Hold down the fire button for continuous spray. Excellent for crowd control and sustained damage.
    • Burst-Fire: Fires a short burst of rounds with each press. More ammo-efficient and precise for single targets.
  • How to Change Mode: Select the M4A1 in your inventory and choose "Customize" or "Change Mode" (exact prompt may vary by version).
  • Strategy Tip: Use Auto-Fire for large groups of zombies or Nemesis, and Burst-Fire for more precise shots against Hunters or Lickers to conserve ammo.
• Western Custom (Jill's Unique Handgun):
  • Location: This powerful handgun is a reward for defeating Nemesis in specific encounters. It is often found after the first or second Nemesis battle (e.g., outside the RPD or after the Clock Tower battle).
  • Features: The Western Custom is essentially an upgraded Handgun. It boasts higher damage per shot, a faster firing rate, and a larger magazine capacity than the standard Handgun. It's an excellent choice for conserving more powerful ammo for Nemesis and bosses, while still being effective against regular zombies.
  • Strategy Tip: If you manage to acquire this, it can significantly reduce your reliance on the standard Handgun and its limited effectiveness.
• Mine Thrower:
  • Location: Typically found in the Dead Factory or the Waste Disposal Plant, often in a storage room or laboratory area.
  • Features: This unique weapon fires mines that stick to surfaces or enemies and detonate after a short delay or when an enemy gets close. It's excellent for setting traps or dealing with slow, powerful enemies.
  • Strategy Tip: Place mines strategically in narrow corridors or before entering rooms where you anticipate strong enemy encounters. It's particularly effective against the Grave Digger or Nemesis if you can lure them into a minefield.

General Strategies for Upgrade Acquisition & Management

• Prioritize Early Upgrades: The sooner you acquire and combine weapon parts, the longer you benefit from their enhancements. The Assault Shotgun, in particular, is a game-changer for early-game combat and can make subsequent Nemesis encounters more manageable.
• Inventory Management is Key: Weapon parts take up valuable inventory slots. Plan your routes and item pickups to minimize backtracking, especially when carrying multiple key items. Consider using item boxes to temporarily store parts if your inventory is full, but remember you'll need them in your personal inventory to combine.
• Be Prepared for Combat: Many weapon parts are located in areas with significant enemy presence or even mandatory Nemesis encounters. Ensure you have adequate health, ammunition, and a clear understanding of the area's layout before venturing to retrieve them.
• Thorough Exploration: While this guide provides specific locations, always thoroughly explore every room, corner, and interactable object. Sometimes, parts can be subtly placed or require a specific action to reveal.
• Live Selection Impact: Be mindful that certain Live Selection choices (e.g., "Fight Nemesis" vs. "Run Away") can sometimes alter item placements or access to certain areas, potentially affecting when and where you find weapon parts. If you're struggling to find a part, consider if a previous choice might have influenced its location.
• Ammo Conservation: Even with upgraded weapons, ammunition is a finite resource. Use your most powerful weapons and their upgrades for the toughest enemies (Nemesis, Hunters, Lickers) and rely on your handgun for regular zombies to conserve precious special rounds.
