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...

First it was the bird flu. Then it was the swine flu. Guess what's next? That's right: the zombie flu! You are a white blood cell. Your must protect the red blood cells. One way to do this is to bump them out of harm's way. The other way is to destroy the zombie viruses by moving over them. To help you do this, you can slow down the viruses or shrink them by shooting enzymes at them or by using Freeze or Time Bombs. Also, pick up as much RNA (green spots) as you can. There are 3 types of zombie virus: Dissolver (looks like a mouth): Destroys red blood cells; must be shrunk before they can be eliminated; can also shrink you and make it temporarily impossible to shoot Eater (looks like a veiny eyeball): Grows by eating red blood cells Spreader (looks like a black and yellow ball): Turns red blood cells into zombie viruses
