Things You'll Need
Instructions
Begin the campaign story mode on any difficulty. Use the BSAA emblems guide provided in Resources to find all 30 BSAA emblems. Shoot these emblems to unlock them. Upon completion of the game, Sheva's Tribal Outfit will be available for use in the story mode.
To unlock the tribal costume in the Mercenaries mode, begin the Mercenaries mode and complete every stage until you unlock Stage 5, the Missile Area. To unlock the next stage requires a B ranking, which requires 20,000 points in solo mode and 40,000 points in duo mode.
Once Stage 5 is unlocked, complete this stage with an A ranking. This requires a total of 40,000 points in solo mode and 80,000 points in duo mode. Once this is done, the tribal costume for Sheva is available for use in Mercenaries mode.
