From Battleborn Wiki
Battleborn includes multiple Progression Systems. Playing either Story Mode or Competitive Multiplayer Modes will earn you XP towards temporary Helix Augmentations as well as persistent Command Rank and Character Rank levels.
- Helix Augmentations: During a single Competitive match or Story episode, each level you gain activates a new Helix augmentation opportunity - all the way to level 10. Each level has two augmentation choices and a character’s Helix resets at the beginning of a new match or episode, meaning you can tailor your character’s abilities to the situation at hand.
- Character Rank: Each character ranks up the more you play them, up to rank 15. The Character Rank levels persist across all Modes, and unlike Helix augmentations, this experience never resets. Increasing the Character Rank unlocks Mutations which are extra Augments that become available on the Helix Menu. The higher the Character’s Rank, the more Helix Augmentations, Taunts, Titles, and Skins you unlock for that character.
- Command Rank: Command Rank persists across all modes and all characters played. Every Competitive match (excluding bots) and Story episode grants XP towards your player Command Rank. Rising through the ranks will unlock Heroes, new Gear options, Titles, and more – all the way to Command Rank 100.
