Classic Pokemon fans anxiously awaiting the November 21st release of Pokemon Omega Ruby and Alpha Sapphire can now get their hands on a new demo to see the latest additions to the upcoming video game.

This new demo is only available through special promo codes found in the newsletter for the Pokemon Trainer Club. If you're not a member, you have until October 19th to sign up.

The Pokemon Trainer Club allows players to connect through the Pokemon Global Link, play the Pokemon Trading Card Game Online, and more. It's rumored that demo codes will also be available through other means soon.

Pokemon Omega Ruby and Alpha Sapphire are remakes of the 2002 Game Boy Advance games Pokemon Ruby and Sapphire. These updated versions will be exclusive on the Nintendo 3DS and feature new platyable character designs not available on the originals. A video released at the Electronic Entertainment Expo earlier this year showed off gameplay footage and new Mega Evolutions for Sceptile and Swampert that weren't available in the recent Pokemon X and Y game.

But a brand new video trailer released this week shows off even more new content to anxious fans. The Eon Pokemon, Latios and Latias, display their new abilities as they Mega Evolve into Mega Latios and Mega Latias. There's also more information on special Mirage spots that allow you to find rare Pokemon in the game thanks to the Area Nav.

"The Area Nav allows you to see exactly what Pokemon can be caught along each route (they'll pop up as silhouettes on your mini-map after you encounter them the first time), and will tell you if you've managed to catch all of the Pokemon available on the route," according to a Gamespot interview with game director Shigeru Ohmori. "You'll also have visual cues on your main screen--you'll sometimes see a Pokemon's tail poking out of tall grass, and if you can sneak up to it (by gently pushing on the 3DS' control stick), you can attempt to battle and catch it."

Despite the new Mega Evolutions introduced in these updated games, there will be no entirely new Pokemon introduced. But it's important to note that, for the first time ever, you'll actually be able to catch every Pokemon on the 3DS through a combination of X and Y, and Omega Ruby and Alpha Sapphire.

Pokemon Omega Ruby and Alpha Sapphire will release on November 21 in Japan, North America, and Australia, and on November 28 in Europe.
