Multiplier System : Bakraid features another scoring system that alters the amount of points gained from enemy destruction by modifying the base point gain from enemy destruction with a specially acquired incremental multiplier. The multiplier system is the more important of the two scoring systems as it is the system that can contribute to almost 80% of your total score, and is centric to the release of the special 100,000 points medals. However, the multiplier system is also the most difficult to get to grips with and exploit, as it requires a lot of pre-planning on the player's part with regards to stage and boss strategies in order to maximize potential point gains. The multiplier system in essence features an incremental multiplier that is gained by destroying LARGE enemies. You can continue to increment the multiplier up to a max of 64x, via this simple table (the number in brackets refers to the amount of large enemies destroyed to reach that multiplier stage) :
2x (destroy 2)
64x (7 and more)
