The new Super Smash Bros. is not the only Nintendo game that 3DS owners will soon have the opportunity to play ahead of release. Nintendo today announced a "special" demo version of Pokemon Omega Ruby and Alpha Sapphire that will let fans transfer some content into the full game, although it's being very coy with the details.

According to Nintendo, the demo will contain "gameplay that players won't experience anywhere else." It didn't elaborate on exactly what it means by that, but did tease that a "familiar" Pokemon that can now Mega Evolve can be obtained while playing the demo. Once the full game is out, this Mega-Evolved Pokemon--along with unspecified items you'll obtain while playing the demo--can be transferred to your copy of Omega Ruby or Alpha Sapphire. Details for doing so will be revealed "soon."

There's no word yet on when the demo will be released, but you will need a special code in order to download it. Again, Nintendo isn't saying how you'll get one right now; that information is also coming sometime "soon."

In addition to the new trailer you can watch above, Nintendo today announced a raft of details regarding Omega Ruby and Alpha Sapphire, which are 3DS remakes of the Game Boy Advance Ruby and Sapphire games. This includes Pokemon Bank and Pokemon Global Link support for the remakes, as well as the fact that Legendary Pokemon Rayquaza will be available.

It also revealed the new abilities that Primal forms of Groudon and Kyogre (Ruby and Sapphire's respective Legendary Pokemon) will gain when undergoing Primal Reversion. As explained by Nintendo:

Primal Groudon gains the Desolate Land Ability, which changes the weather condition to extremely harsh sunlight. Opponents cannot change the weather condition during extremely harsh sunlight, meaning moves like Rain Dance, Sunny Day, Sandstorm, and Hail will fail, and Water-type attacks will fizzle out. Abilities like Drizzle, Drought, Sand Stream, and Snow Warning will also fail to activate. Groudon can unleash a move unique to it alone, Precipice Blades, a powerful attack that can hit multiple opponents with an upward surge of sharp rocks.

Primal Kyogre's exclusive Ability is Primordial Sea, which changes the weather condition to an oppressive heavy rain. As with extremely harsh sunlight, opponents cannot change the weather condition during heavy rain. The Abilities Drizzle, Drought, Sand Stream, and Snow Warning will fail to activate, and Fire-type attacks become ineffective as well. Kyogre has its own move that only it can use, Origin Pulse, an attack that can slam multiple opponents with water massed into ballistic orbs.

Omega Ruby and Alpha Sapphire launch in North America on November 21.
