Rock Rush: Undervaults    Hidden inside a huge network of natural caverns is this mysterious artificially-built series of rooms, each filled with puzzles, dangers, and of course lots of pristine gemstones! Will you be able to make it through and escape with your fortune? Dig through bug-infested caves dodging boulders, triggering magic walls, and collecting diamonds until you have enough to open the exit. But it doesn't stop there. Depending on which version of Rock Rush you play there may be even more challenging elements to figure out before those gems come within your grasp...
