All CyFrames have three equipment slots to begin with, and what is placed in these slots determines the character's fighting abilities. From here, players can mix and match what type of parts they want to use, with available techniques dependant on what they have equipped to their CyFrame. All battles and exploration take place inside ruins, which are randomly generated level by level. Progress is made by going floor to floor, with dungeons ranging from around 15 floors to nearly 30. Traps and monsters are randomly inserted into every floor, and a variety of tools help you find your way around them with little trouble.
Battles begin when the player comes into physical contact with an enemy.
The angle of contact is worth paying attention to, as a careful approach from behind can result in a few free rounds of attacking. The closer an attacker to his target, the more damage they will deal. Input is entirely menu based, with the standard RPG-fare choices of attacking, defending, using an item, and using a special move. Special moves, the aforementioned techniques learned via skill points, can be used when the character has sufficient tech points. These can be acquired through regular attacks or using restorative items, although it's easier to run out of them than you may think.
