To attain 100% completion in The Lost and Damned, the player must accomplish all of the following:
- Complete 22 storyline missions (Clean and Serene to Get Lost).
- Complete 25 Gang Wars side missions.
- Complete 12 Bike Races side missions.
- Complete 10 Angus' Bike Thefts.
- Terminate all 50 seagulls.

Rewards[]
Completing The Lost And Damned to 100% gives players the ability to buy an unlimited amount of ammunition for all weapons, although it still costs the same as before. NOTE: When purchasing, e.g. "Infinite" Rounds of Ammunition for a Pistol, saving, then re-loading that profile, will result in the Numerical Value of Ammunition being lowered to the standard for that particular Weapon. Thus, every time the player buys "infinite" ammunition for a weapon, save, then re-load, they won't have that "infinite" ammunition from before.
