Shin Megami Tensei X Fire Emblem, or Genei Ibun Roku #FE, recently got some updates on the official website, which includes some screenshots and videos that detail the game’s world, dungeons, and battles.

Players will go through a gate from Tokyo to visit the “Idolsphere,” a world filled with various gimmicks, many enemy Mirages, and other dangers that will get in the way. You’ll need to face these challenges with the group of Mirage Masters in order to take your next steps through the game’s story.

There are various gimmicks for each area. For example, at the “106” (Shin Megami Tensei X Fire Emblem’s version of “Shibuya 109”) you’ll need to control a giant mannequin arm in order to get through the floors and reach the top floor’s boss.

Battles start when you run into enemies in the Idolsphere.The battles are command-based, and characters will attack when you give the order. By hitting an enemy’s weakness you’ll get to do a “Session Attack” to be able to land more attacks.

Upon winning fights you’ll get experience points, skill points and Performa. Getting more skill points will allow you to learn more skills, and Performa is used as material to make new weapons. By completing battles you’ll continuously grow and upgrade equipment.

And finally, the above video gives us a look at what it’s like to explore the world. As you can see, key characters are always visible and you can interact with them, otherwise they’re a bunch of colorful silhouettes.

We then get to see the place get pretty dark with an ominous vibe going on. Itsuki talks to a “game otaku” who says “who cares about music and video games… going home is also a pain in the ass…” and Tsubasa says “I want to help my sister… Please, Itsuki, help me!”

Shin Megami Tensei X Fire Emblem will release in Japan on December 26, 2015 for Wii U. You can catch up on the latest character introduction video with the red-haired hero Toma Akagi in our previous report.
