In Parasite Eve II, at the end of the game (on any mode) the player is awarded a score based on all EXP earned in that playthrough. This score determines which rank the player is awarded, with S being the highest, then running from A down to L, being the lowest. Each rank opens up new weapons, items, and ammunition available for immediate purchase in any shops in the game during any subsequent Replay Mode. The item awards are ONLY available in Replay Mode. They will not be available in Bounty, Scavenger, or Nightmare modes (other than what is normally for sale).
