The object of each level is to retrieve the nuke hidden in the cave, and bring it to the exit point.
To play Caves of Andromeda, use the following keys on your keyboard to control your ship:
Your ship has a deflector shield, which will protect you from collisions with the walls, and enemy weapons. When this shield is exausted, your ship will be destroyed. You start the game with three ships. If the nuke is damaged while you are towing it, your shields will be depleted at a faster rate.
To pick up the nuke, just fly your ship close to it and your tractor beam will lock on. Flying the ship will be more difficult when you are carrying the nuke, and you will not be able to pass through small passages with it.
