The battle system in Hyperdimension Neptunia mk2 is turn-based by unit, where each character's turn comes based on their speed. Characters roam around the established battlefield within their movement range. Players can choose for the characters to either attack, guard, or use skills. Depending on what option is chosen, the range of an attack or skill's effect will depend on the skill or the equipment the character has. Characters also spend AP to attack enemies or use an item. When executing Skills, they expend both AP and SP.
