Lady Sia is a platform game with action-adventure elements made by RFX Interactive for the Game Boy Advance. It was published by TDK Mediactive, released in the USA on October 15, 2001, and released in Europe on October 19, 2001. Lady Sia is one of the few original games produced by RFX Interactive. The game takes place in a fantasy world where the player assumes the role of the She-Ra/Xena-esque warrior princess, Lady Sia. It is her task to defeat the T'soas, a race of creatures created by the evil warlock Onimen who has declared war on the other realms. Her quest leads her through four different realms, the last one being the home continent of the T'soas themselves. A sequel was planned for the GameCube and GBA in 2003 but was cancelled due to TDK Mediactive being purchased by Take-Two Interactive that same year. Gameplay Lady Sia is a traditional platformer with action-adventure elements. As such, players have to watch out for numerous enemies as well as make sure not to fall off of the platforms. The world Sia must cross is divided into four areas, each of which are divided into four levels, a main boss fight, and a bonus level. Levels focus on either fighting or acrobatics. Sia has three lives per level, but the player can temporarily acquire more by collecting gems. If the player loses a life, he or she must restart at the beginning of the level or at the last checkpoint. Checkpoints are found halfway through each level and usually depicted as golden whirlwind images that turn into an image of Sia when activated. If all lives are lost, Sia is "thrown in jail" and the player receives ten seconds to decide whether to restart the level or quit. A perfect score on a level is 100 points: five points per health point, one point per magic point, one point per collectible gem, and five points per freed prisoner. Getting a perfect score for each of one area's four levels grants access to the bonus level. In addition, Sia must prove her worth to the other leaders in the first three levels of the second area by battling two of them and racing a third. Sia's status after these boss battles has no effect on her score for that level. Defeating the main boss in each level grants access to the next area.
