Pier Solar [1st Edition] - In-Box - Sega GenesisPhelios consists of seven chapters, and in each, you must defeat Typhon's minions using your sword which can emit fireballs at them. However, holding the fire button down for a few seconds will charge the sword; and upon releasing it, it shoots a larger fireball that does a fair amount of damage. During the game, you collect items that increases your speed and give you more firepower.
