How do i get loyalty reward? Do i need to have both savegame or i just need 1 savegame to get loyalty reward? Right now i just has borderlands 1 savegame Is there any different reward from BL 1 or 2 save game ?
The rewards depend on what kind and how many previous games you have.
If you have a borderlands 1 savestate, you get a special weapon and a special skin, also a bunch of moonstones. With a borderlands 2 savestate, you can be happy about a special weapon, another special skin, a few moonstones and badass points. When you got both, you get everything, plus even more moonstones.
