The Hazardous Ruins are dangerous ruins located northeast of Portia in the Collapsed Wasteland and in the Eufaula Desert. The Hazardous Ruins is home to dangerous enemies and traps, causing the ruins to be strictly prohibited from trespassing. The Civil Corps are responsible for closing off and opening the entrance to these ruins.
To enter the Hazardous Ruins in the Collapsed Wasteland, the player needs to prove his or her strength by sparring with a Civil Corps member, the player can then enter the Collapse Wasteland and find the Hazardous Ruins.
For the Hazardous Ruins in the Eufaula Desert, players will need to complete the Mission: Rescue in Ingall's Mine before being allowed to enter the ruins.
Entering the ruins consumes a certain amount of time, although time inside the ruins freezes. Each time the player enters another level, time is consumed. However, time is not consumed when advancing to the next floor.
Advancing to the next floor requires meeting one of two criteria:
- simply navigating through obstacles or
- defeating all enemies in the floor.
The player has the option to quit in the middle of a run to return to the overworld.
