Ah, what a grand day, indeed. We present, Solgaleo and Lunala, the two newest legendaries in the Pokémon universe. Solgaleo (as seen on left in picture above) will star in Pokémon Sun, and Lunala (right) in Pokémon Moon. Both look like they could deal out a massive whooping on lil Popplio. Here's the new trailer which features the legendaries, as well as new gameplay footage, and a look at the new Pokédex:
In Sun and Moon all players will get a Pokédex inhabited by the ghost-like Pokémon Rotom, who can possess/inhabit objects and machinery.
“It does much more than record Pokémon info—it sparkles with its own personality. The Rotom Pokédex shows your current location and your next destination, and it also gives you advice on where to go next, based on the conversations you have with others! It’s likely to be of great help to you in many parts of your adventure.”
Lastly, here's a detailed look at Aloha: the Hawaii-inspired region of Sun and Moon:
Here's the developer, Nate's description of the game:
Pokémon Apex is developed with an adult Pokémon fan in mind. The game contains some adult dialogue (some swearing) and themes (death, abandonment), and some minor horror elements. Furthermore, the game is intended to be somewhat difficult, meaning that you will need to think about your strategies and make conscientious choices about your team in order to progress. Playing through the game haphazardly will get you into trouble.
Also, this game is for people who prefer to take their time in games to explore their environment and uncover hidden details. There are lots of small details hidden throughout the game, as well as secret areas and items that reward meticulous players.
The game's still in development, but you can download it over here to try it out!
