Senran Kagura 2 introduces new systems like the Pair Battle system along with new and improved costume and AR features. Marvelous also shared a look at another new mode, the “Wraith’s Den,” that lets you take on monster-filled stages for some neat loot.

The way the Wraith’s Den works is pretty simple. It’s a grid-based stage system that will have you take on rooms full of monsters. By clearing out the room, you can advance to the next stages.

Once you clear a stage, any of the adjacent rooms can be accessed, afterwards. In order to clear a stage, you’ll need to reduce the number of monsters (located on the top-left of the screen) to 0, or defeat the boss of the stage.

What makes this mode a little tricky, is that the characters keep the same amount of health they had left over from the previous stage, so health points become a major factor. However, there are three ways to recover health in the Wraith’s Den.

The first and simplest way is by transforming, which allows you to completely recover your health once. The second way is by activating Meiken, where the character also gains a temporary buff along with a draining effect, but it also takes away your scroll meter, so it comes with a risk.

The third way of recovering health is by defeating certain enemies that drop Onigiri rice balls; however, there are stages where these enemies won’t appear at all, so you might not want to rely on having those around.

By clearing certain stages, you can acquire all kinds of different weapons. These weapons aren’t restricted to the characters you select, so you can take on the Wraith’s Den with any of your favorite girls.

Senran Kagura 2: Deep Crimson is slated for release in Japan on August 7, 2014 for Nintendo 3DS.
