Neptunia x Senran Kagura: Ninja Wars/Gameplay

Difficulty
The difficulty setting can be changed in the System Menu except while inside of a dungeon. In hard mode, regular enemies are as hard as bosses. In easy mode, all enemies take massive damage.

Treasure Boxes
Dungeons have two types of treasure boxes that contain items, normal and locked. Locked treasure boxes requires a Stealth Key to open. Each treasure box can only be opened once and the world map tracks how many have been acquired in each dungeon.

Market Street
The Market Street is where you can buy and sell Spirit Gems, items, and equipment. More items become available as you progress through the game.

Kumotsu Shrine
Kumotsu Shrine is where you can accept requests and obtain rewards for completing them. Once accepted, you will immediately move to the dungeon, so you need to prepare prior. More requests become available as you progress through the story and all requests can be repeated. Special requests can be obtained from NinChat and will have two types of valuable Dogoos. Gorgeous Dogoos give more experience when defeated and Pot Dogoos drop multiple items. Special requests will disappear from the list whether you successfully complete them or not, but you can talk to the requestor in NinChat to make them appear again.

Kumotsu Shrine also has a treasury where you can view event CGs, character info, movies, events, and play BGM.

Peaches & Cream Meditation
Peaches & Cream Meditation is a mini-game where the character sits on a large peach and mediates. You have to fill the Peach Gauge by keeping a ball on the curved balance bar. If you succeed, you gain various effects for the leader and partner. When a Patience Challenge occurs, a tilted silhouette of the character appears. Holding the ball in the silhouette will greatly increase the Peach Gauge. On higher difficulties, the peach will grow larger after the Peach Gauge is filled and the next stage appears. Peaches & Cream Meditation requires a fee to play, but you can use a Time-Saving Ticket to skip it and receive the effects right away.

NinChat
NinChat is where you can talk with characters. Characters with a "!" will give an item, unlock a special request, or an event will occur.
