The mod

How it plays

All captures are in-game.

NEW GUNDEX ENTRY! announcement for the Unkempt Harold, with Savage Lee down nearby.

New GunDex entry!

The first time you loot an item, GunDex registers it and announces the new entry.

Tiny Tina 100% banner with confetti, in the Handsome Sorcerer's arena.

Milestones

Progress is tracked by category: the base game and each DLC. Milestones mark the way to 100%.

Three GunDex pages side by side: Mister Torgue, Sir Hammerlock with 6 of 13 collected, and Tiny Tina, each with its own title colors.

One page per DLC

The base game and each DLC get their own page, in their own colors. Change page to see what's left to find in each one.

A not-yet-discovered item: question marks and the Bandit logo, in a list where found items and black silhouettes alternate.

Not found yet

Items you haven't found yet show only their silhouette and manufacturer.
