Mastering Maximum Weapon Upgrades in The Last of Us Part II Remastered

Playing The Last of Us Part II Remastered on Grounded+ difficulty changes everything. The margin for error shrinks to almost nothing, and every encounter demands precision. One of the first lessons I learned the hard way is that you cannot rely on pure reflexes alone. You need tools that perform at their absolute peak. That means chasing maximum weapon upgrades before you push into the later, more brutal sections of Seattle.

I have spent countless hours replaying the game, testing different builds and upgrade paths, and I can tell you that the difference between a half-upgraded arsenal and a fully maxed out weapon set is night and day. On Grounded+, enemies hit harder, react faster, and flank relentlessly. A fully upgraded semiautomatic pistol or hunting pistol can mean the difference between surviving a tight corridor fight and watching a loading screen.

Why Maximum Weapon Upgrades Matter on Grounded+

Grounded+ strips away most of your safety nets. Listen to a no damage run, and you will see that every shot counts. You cannot afford to miss, and you cannot afford a weapon that jams or reloads slowly. The upgrade system in The Last of Us Part II Remastered is deeper than it first appears. Each weapon has multiple slots for improvements, from rate of fire increases to stability enhancements and stun upgrades that buy you precious seconds in a firefight.

When I first attempted the game on Grounded+, I ignored the toolbox in favor of raw firepower. That was a mistake. The real value comes from balancing offensive upgrades with utility. A tactical shotgun with a rate of fire boost and a stun upgrade can clear a room, but only if you have the upgrade parts to bring it to full potential. The weapon upgrade bench is your best friend. I spend time at every workbench I find, checking which parts I can slot and whether any weapon needs attention.

The Upgrade Path: Priorities and Trade-Offs

There is no single correct order for upgrades, but I have found a pattern that works well for a Grounded+ no damage run. Early on, focus on the semiautomatic pistol. It is your most reliable sidearm, and a few early upgrade parts can make it far more accurate and faster to fire. After that, I shift to the hunting pistol. It hits hard and benefits enormously from a stability upgrade. A stable hunting pistol lets you land headshots consistently even while moving, which is critical when you cannot afford to trade hits.

Later in the game, the tactical shotgun becomes essential. Its stopping power is unmatched at close range, but it needs a rate of fire upgrade to be truly effective. Without that, you can get overwhelmed by multiple enemies rushing at once. I also make sure to invest in a stun upgrade for at least one weapon. Stun upgrades give you a moment to reposition or line up a finishing shot, and on Grounded+ that moment is worth more than extra damage.

The skill tree complements your weapon upgrades. Maxing out your weapon skills reduces sway, speeds up reloads, and increases damage. But skills cost supplements, and you cannot max everything. I prioritize the weapon skill tree first, then supplement it with stealth and survival skills as needed. The combination of a maxed out weapon and high-level weapon skills makes encounters feel manageable even on the highest difficulty.

All Collectibles and Chronological Mode

An all collectibles run forces you to explore every corner of the map. That is a good thing, because many upgrade parts are hidden in side rooms, behind locked doors, or tucked into areas you might otherwise skip. Chronological mode helps here. It lets you follow the story in timeline order, which means you revisit areas with different characters and sometimes find parts you missed the first time.

I remember playing through Ellie's section and finding a rare upgrade part inside a safe in a hotel room. Later, as Abby, I returned to a similar area and found another part in a toolbox under a desk. Chronological mode makes those connections clearer. You start to recognize the patterns in how Naughty Dog places upgrade parts, and you can plan your route to collect every one.

An all collectibles run also means you will encounter more optional encounters. Those are opportunities to scavenge for materials and parts. I recommend fighting smart, not hard. Use the environment, use stealth, and use your upgraded weapons to end fights quickly. Every bullet saved is a bullet you can use later.

Practical Tips for a No Damage Run

A no damage run on Grounded+ is the ultimate test of your upgrade strategy. You cannot afford to get hit even once. That means your weapon upgrades must be optimized for control and speed, not just power. I always prioritize the following:

• Rate of fire upgrades on any weapon you use in close quarters. Faster shots mean fewer chances for enemies to close the gap.
• Stun upgrades on at least one weapon. The stun effect creates openings that let you escape or finish an enemy without taking damage.
• Stability upgrades on precision weapons like the hunting pistol. A stable aim lets you land headshots without hesitation.
• Reload speed upgrades on your primary weapon. A slow reload can get you killed when enemies are pushing.
• Always carry a fully upgraded semiautomatic pistol as a backup. It is reliable and versatile.

I test every upgrade at the weapon upgrade bench before committing to a run. Sometimes you need to swap parts between weapons depending on the upcoming encounter. For example, before a heavily armored enemy, I might move my stun upgrade from the pistol to the tactical shotgun. Flexibility is key.

The Role of 4K Ultra and Gameplay Walkthroughs

Watching a 4K ultra gameplay walkthrough of a no damage run can reveal upgrade choices you might not consider. The clarity of 4K makes it easier to see where enemies are positioned and how they react to different weapons. I have watched walkthroughs where the player uses a stun upgrade on the hunting pistol to stagger a runner, then follows up with a headshot. That kind of detail is easy to miss at lower resolutions.

A good gameplay walkthrough also shows the upgrade path in real time. You see which workbenches the player uses, which parts they pick up, and how they prioritize. I learned from one walkthrough that the tactical shotgun with a rate of fire upgrade can interrupt an enemy's attack animation. That is a game-changer on Grounded+.

Ultimately, the goal is to reach a state where your weapons feel like extensions of your character. When you have maximum weapon upgrades across your arsenal, you can focus on positioning and decision-making instead of worrying about whether your gun will jam or reload in time. That is the point where the game opens up and you can play with confidence.

So spend time at every weapon upgrade bench. Prioritize upgrade parts. And never underestimate the value of a stun upgrade or a rate of fire boost. On Grounded+, the difference between surviving and dying is often just a single upgrade slot filled or left empty.
