Guide a robot through treacherous territory to get gems and avoid the big bad meanies. Basically what this is is Chip's Challenge with a gun. That's not to say it's a bad thing, though. There's a bit of Dig Dug thrown in too with rocks that fall once you dig (read: shoot the dirt) under them. Your robot can get killed by an enemy, have a rock fall on them, get blown apart by explosives, so it's very dangerous for mr. robot. There's a good thing that's like Chip's Challenge, and that's in the form of passwords. Say I'm stuck on level 6 (I am.) I can just go online and get the password for level 7. It's cheating, but I can't pass it! So, what it all boils down to is : Crystal Mines II - like Chip's Challenge, but different in a few ways. So, for this game.
