Shadow Tower is a first-person dungeon crawler developed by FromSoftware.
The continent of Eclipse, here lies the holy land of Zepter. In this land a sealed tower is guarded by kings of surrounding nations.
Deep in the forest, beside an ancient tower, there was once a town.
"Darkness swallowed all and closed the gate."
What is the meaning of these words...
Darkness came again and Zepter was devoured.
A young warrior came to challenge Darkness.
Shadow Tower can be considered a missing link between King's Field series and Demon's Souls. The "old style" dungeon crawling is mixed with more "modern" design choices like large amount of various equipment and manually increasing character stats.
Playing Shadow Tower first requires you to acquire a copy of the ROM, and the latest build of Duckstation.
From there, commonly asked questions and their answers can be found on the FAQ page.
