Pokémon Omega Ruby and Alpha Sapphire launched last Friday, promising new Shiny Mega-Evolutions for its bestiary. This 20-minute video shows off all of their animations.
Players are already entitled to a Shiny Beldum holding a Mega Stone, thanks to an in-game distribution that began with the game's Nov. 21 launch. There are 47 additional shiny megas, noteworthy among them Shiny Primal Groudon, Shiny Primal Kyogre, and Shiny Mega Rayquaza.
Polygon scored the reboot of the 2002 Game Boy Advance title an 8.0, saying its "multitude of monsters and increasingly complex type-matching strategies" make the game worthwhile despite a rather standard iteration on the series.
