 The programmers and designers worked hard to use every bit of power from Sega's hardware.Iuchi did not include power-ups in "Radiant Silvergun" because he felt they were distracting, and he often found himself dying when trying to manage different weapons and items.To combat this, he made the game progress simply through shooting and dodging, and mapped weapons to individual buttons and button combinations instead of needing to press a button to cycle through weapons.
