Modifiers, found on equipment as lines of green text, cause various effects, such as increased crit chance, increased shot count, or increased fire rate/decreased cycle time. The prefix of a weapon is determined by how many modifiers it has:

Modified: 1 Modifier

Custom: 2 Modifiers

Experimental: 3 Modifiers

Prototype: 4+ Modifiers (Prototype items with 5+ modifiers can only be obtained via admin commands.)

Depending on the zone, the max amount of modifiers on equipment can vary.

• +Bounce: Allows the projectile to bounce one (more) time, resetting range upon contact of a wall and/or floor.
• Penetrating: Allows projectile to go through enemies

• Quick Shot: Increases rate of fire for ranged weapons
• +Max Ammo: Increases the max ammo of a secondary by a certain amount (only applies while it is equipped, but it is multiplied by Bandolier ammo multipliers if present)
• Incendiary: Explosions are replaced by flames that cause 50% of weapon damage every 500 milliseconds. Flames last for 2 seconds before disappearing.
• Barbed: Frags now deal 50% of weapon damage to the first enemy they touch directly.
