The Type N frame is the default and basic Gespenst frame. It’s versatile in any combat situation.
The Type G frame specializes in close combat and melee attacks. (That doesn’t stop it from pulverizing enemies at close range with beam weapons though!)
The Type C frame specializes at long range artillery attacks.
Ability Slot System
There’s a menu where you can organize your abilities/slots. Each pilot and robot has 3 ability slots each.
