The story of Pier Solar tells about Hoston, a young botanist who is on a quest to save his father from a mysterious illness. He hears of rumours that a cure to his father's disease can probably be found in the nearest forest, and Hoston, disregarding his mother's warnings, sets out to find the cure.
The game is a classical console-RPG with round-based battles, similar to the Phantasy Star series on the Sega Genesis. The gameplay involves exploring different locations, interacting with non-playable characters, and engaging in turn-based combat.
Pier Solar was released for the Sega Genesis on 20 December 2010.
