As part of the Solar System Recources Research team you have landed on one of the Saturnian system moons. Prospecting for the precious minerals that Earth so desperately needs you have driven away from your lander craft to take readings and soil samples for analysis. A routine enough task until.... The bio-sensor flashes its warning- there are creatures moving nearby! You urgently head back for the lander... and getting CLOSER! They dart nervously towards your crawler, spitting deadly acid-balls. There is nothing you can do but defend yourself for as long as you can with the crawler's cannon. At least you can still turn the crawler with its one remaining track to aim the cannon, using console keys 1 and 0 for left and right. And the guided photon bolt still fires on the 9 key and is controlled by the 1 and 0 keys - things could just conceivably be worse (couldn't they?). But the situation is desperate. Here they come, in innnumerable waves. How long do you expect to survive before... don't even think about it!
