Introduction

Weapon perks are stat bonuses granted by the weapon in your active hand slot.

Your equipped weapon gains experience when you kill NPCs. You can also give it XP by using Upgrade Parts on it. When enough experience is earned, it levels up, a new perk unlocks, and the weapon's color changes.

Weapon perks vary in effectiveness depending on their rank. Weapon perk ranks you get are heavily influenced by item luck.

The first three weapon perks that unlock as your weapon gains levels are always the same for a specific weapon; see Weapons for details.

The fourth perk can be chosen via a dialog window once unlocked. However, if you level up your weapon using Upgrade Parts, this perk will be random.

The fifth perk is always random.

The sixth perk, known as the "legendary" perk, is selected from a separate table of perks and only applies against NPCs.

Every weapon can be upgraded by Roger (Salt Lake City) with a T4 part, or by Cotsford (Las Vegas) with a "Wattz" Fusion Core to gain one additional perk.

1 10,000
2 75,000
3 150,000
4 1,000,000

Weapon experience

The total amount of gear XP required for a weapon to level up depends on its tier, type, and current level.

Total XP required for a weapon to level up = Base XP requirement * XP requirement multiplier

The tables below show (1) the base gear XP required to level up your weapon depending on its tier, and (2) the base gear XP requirement multiplier by weapon type, followed by precalculated results of its application.

Note: The XP multiplier only applies to levels 1–4. For levels 5 and 6, all weapon types use the base (100%) values.

Itemized gear upgrades

There are two item types that can help your gear achieve the optimal perk configuration: upgrade parts (which provide an immediate gear XP boost), and gear mod upgrades (which have a chance of increasing the rank of your already unlocked perks).

Weapon XP boosters

Found mostly in dungeon lockers, Upgrade Parts add experience directly to your weapons. Note that any perks unlocked via this method will be randomized, even if you would normally be able to select the one you want.

To use Upgrade Parts on an item: (1) place the weapon on the ground; (2) click and hold the left mouse button on it; (3) from the drop‑down menu, select the bag icon; (4) in the inventory window that appears, click on the stack of Upgrade Parts you wish to use.

Weapon perk rank upgrades

If the rank of the perks on your weapon could use a little tune-up, there are several items that you may find interesting, see the table below.

To use any of them: (1) place your weapon on the ground; (2) click and hold the left mouse button on it; (3) from the drop‑down menu, select the bag icon; (4) in the inventory window that appears, click on the item you wish to use. Alien weapons are only compatible with GMU1000.
