*DR means Destruction Rate

Boss tip:

Shoot the head only (it will result in less DR) and dodge lasers, or just destroy everything boss has to gain 100% DR

After fight begins, the boss will shoot out basic projectiles. Absorb them with Radiant Sword (Right trigger on Sega Saturn controller or Xbox if you are on PC or Xbox 360) and use Radiant Sword again to deal massive damage

also forgot to note that there is zero saving system (except for weapon stats) because it is obviously hardcore shmup
