The Sacred Rings is the sequel to 2004 adventure title
Aura, though there isn't really anything on the box that says that. You pretty much have to know the original game and recognize the names and situations from the box description. If you haven't played the first one, don't worry. There is an intro movie that runs through the plot and gets you caught up. Here is a brief run through of
Aura's plot in case you didn't get to play the first game, or you just need a refresher.
An evil ruler is seeking out several sacred rings and two artifacts known as Tetrahedrons. This king is hunting them down because they are supposed to grant the owner unlimited power and immortality. These artifacts are safely stowed away and maintained by an order called The Keepers. When The Keepers' land is ransacked, a young follower named Umang is given the treasures and told to keep them safe. After being hunted by the opposing force, he is transported to a strange new world. This is where the game starts off.
The Sacred Rings hits the ground running with you having to figure out how to work a strange metal "house" that seems to have an engine room and runs on crystal batteries. It isn't long before the the evil king shows up and forces you to learn how to operate the moving house quicker than expected.
This game will take you across several locations and let you explore the new world in which you find yourself. You will even go full circle and return to the Keeper's Tower, but now it is under the rule of your enemy and you have to get past all of your foes to try to set everything right again.
The Sacred Rings is a good followup to the previous game. When I first got the game to review, I didn't realize that it was a sequel and when the initial movie ran its course, I couldn't help but feel it all sounded familiar. It took a little digging through my older adventure games, but I was eventually able to jog my memory and fill in the blanks.
