Archetype Icons - these are some of my oldest designs, and I am happy they still exist in the game. Characters fall under one of three Archetypes which determine their general play style and role within a group.

Weapon Class Icon Concepts - the style of our single color graphics has changed a lot over the course of development and these are some of the earliest takes on our weapon classes (we even had a bow ranged weapon class for a time).

Modifier Icon Concepts - many of these concepts evolved into our current mutator and buff iconography.

Reinforcement Perk Icon Concepts - in an early design, the player would be able to pick a perk to infuse into their weapon when Reinforcing it, which would alter the course of its progression.
