Skylanders: Swap Force has been a big hit for Activision as the combination toy line and video game has captured the imagination of children as well as some adults. The game was released before some of the action figures were released, causing some parts of the game to be locked away until those figures became available. However, now, as Kotaku reports, the last figures needed to get 100 percent through Skylanders: Swap Force are now available.

Rubble Rouser and Stink Bomb are the final two characters needed to complete the game, and they are now available at Toys R Us locations around the United States. The reason these figures are necessary for completing the game is each character's unique elemental characteristics. Each Skylander character has an element associated with them, and special gates require different combinations of elements for players to pass through them. In addition, each Skylander has a special transportation ability that is needed to unlock different minigames.

Rubble Rouser is the first figure in the Swap Force line of toys with the Earth element. The character's release now allows each and every Earth-based gate in the game to become unlocked. Stink Bomb is the first Skylander with the sneaking transportation power, so the figure is needed to unlock several minigames.

While it may be strange that Activision would release Skylanders: Swap Force without having all the characters needed to complete the game available at the same time, it is smart way to make fans of the game take notice and stay interested. New Adventure and Battle Packs have also been released for the game, providing even more new content for players to check out.

Skylanders originally started life as a spinoff to the classic Spyro franchise, but has since become a original franchise with several different characters that players can collect. Here's how the game works: fans buy the game along with a special USB stand that can be used to import new characters into the game with. This allows players to collect their favorite characters and use them in the game and have action figures that they can play around with in real life. In addition, it forces users who want to complete all the content in the game to buy several different figures and spend hundreds of dollars on the franchise.
