Sword of Sia: Lady Sia 2 (aka Lady Sia II) is a cancelled action adventure / platform game that was in development in 2002 / 2003 for the Gameboy Advance by RFX Interactive and it would have been published by TDK Mediactive (as was the first game). It seems that Lady Sia 2 was almost complete (it was even rated by ESRB), but in 2003 RFX had to close down and TDK Mediactive was acquired by Take-Two Interactive. Lady Sia 2 vanished with the closure of its development studio and publisher.
The original Lady Sia was released in 2001 and it was one of the first titles published for the new at the time Game Boy Advance. The game was received well by the press and gamers; this cancelled sequel could have improved the formula its predecessor established and it’s a shame that we’ll never be able to enjoy it. We can only hope that a playable prototype will be leaked in the future.
A Lady Sia 3D prototype was also in development for the Playstation 2 and GameCube, but it was canned too.
