A Dungeon is an area where you will have to face unusual monsters and mysterious traps. Each Dungeon is different and located on various planets.

There are lots of parts and items hidden in a Dungeon as well as a boss monster lurking at the end. It is important that you cooperate with your friends to make it through in one piece.
Also, you will not be able to meet other players in the dungeon if you do not activate the floor gate together.

Once you have entered the Dungeon, there is no turning back. When your robots have all been destroyed in the dungeon, you will lose all of the parts, items and EXP that you have earned while in the Dungeon. (The same situation applies when you use the give up function)
If you wish to leave the Dungeon as soon as possible, please use the "Escape Gate".

There are gates in the dungeon that will display numbers.
To open the gate, you must use a "Stone". However, you will need the same colored stone as the number on the gate in order to activate it.
The Stones you have obtained lose their effect once you have moved to a different floor.
