Battlerock Galaxy
The Battlerock Galaxy is a galaxy in the Wii game Super Mario Galaxy. The galaxy contains many floating metallic saucers and planet-sized rocks with Cannons. The Battlerock itself is a huge rock studded with cannons that occasionally fire at Mario, and the inside contains many technical contraptions. Many robots and Bob-ombs appear in the galaxy. The galaxy also contains an area where three Lumas are being held. Topmaniac is a boss here.
Enemies
Levels
Battlerock Barrage
Mario begins on a small disc-shaped platform near four other similar platforms in space. His first task is to collect the five blue Star Chips on these platforms. Collecting the Star Chips will cause a set of Pull Stars to form that lead Mario to a Launch Star. Mario will land on another small platform and must bounce on an enemy to reach a higher platform. Star Spin the blue screw on this platform to start it moving. Mario will have to dodge the cannon blasts and electric walls as the platform moves, running on the underside if necessary. When the platform stops, Mario can jump onto the platform that contains a Power Star in a cage. He must lure one of the nearby heat-seeking Bullet Bills into the cage and grab the Star.
Breaking into the Battlerock
Mario begins this level on the same set of small platforms. One platform contains a neverending supply of Bob-ombs, and another has a cage with a Launch Star, so Mario must throw a Bob-omb at the cage to free the Launch Star. Mario will launch onto a Chain Chomp-infested planet that contains a cage with a Luma, a cage with a Rainbow Star, and a Bob-omb supply. Use the Bob-ombs to break open the Luma's cage, and he will transform into a Sling Star. This will sling Mario into a Launch Star, which sends him into a Pull Star minefield. Carefully avoid the mines while using the Pull Stars to reach the Launch Star. The next room contains cannons encased in glass on both ends and a Luma encased in glass floating in the center. Use a Bob-omb to free the cannon, jump in the cannon, and aim for the moving glass chunk. Two hits will free the Luma, who will turn into a Launch Star. The Launch Star will send Mario to a place with a Bob-omb supply and a cannon in a case. Free the cannon and jump in. The Power Star is circled by moving platforms, so aim carefully and grab it.
Topmaniac and the Topman Tribe
Mario lands a small platform once more, this time surrounded by only two others. One platform has a Rocky Wrench with a Pull Star near it. Use the Pull Stars to reach another platform, then use the Sling Star to reach a moving platform. This platform moves through a minefield, so dodge all the mines and use the Launch Star at the end. The next platform contains a Luma trapped by an electrical barrier and a red Topman. Star Spin the Topman into the electricity to free the Luma, who turns into a Launch Star. This will launch Mario into some platforms, one of which has a Warp Pipe. The Pipe sends Mario into a 2D area. Spin the arrow to reverse gravity and go right, dodging the firebars and carefully navigating the spinning platforms above the lava. Spin the arrow to flip gravity again and start moving right. Don't jump or stand on top of the moving platforms, because if Mario enters the area of downwards gravity he will have to redo the previous section. Fall upwards through the gap and run right, dodging the crushers. Bounce on the trampoline to reach a Warp Pipe, and bounce on another trampoline to reach a Sling Star. This sends Mario into an elevator, and he will end up in a room with an electrical barrier and two Topmen. Spin both Topmen into the electricity to deactivate it and reach a Launch Star. Mario will be launched into the underside of a large platform with many electrical fields and Topmen. Dodge these and walk to the topside of the platform where a Luma Shop and a boss fight await. See Topmaniac for information on beating this boss fight.
Battlerock's Garbage Dump
This is a hidden Power Star found on "Breaking into Battlerock". Proceed as normal, but when Mario reaches the planet full of Chomps, instead of freeing the Luma in a cage, talk to the hungry Luma. Feed the hungry Luma thirty Star Bits to transform him into a Launch Star that will send Mario to a platform full of garbage. The Gearmo on this planet will challenge Mario to use Bob-ombs to take out all the garbage in thirty seconds. The Bob-ombs take ten seconds to explode, so make sure they are placed well and that each one takes out three or four pieces of garbage. The Gearmo will give you a Power Star for successfully completing this task.
Topmaniac's Daredevil Run
This Power Star is accessible when a Daredevil Comet passes over Battlerock Galaxy. Mario will begin on the underside of the large platform containing Topmaniac (see Topmaniac and the Topman Tribe). He will only have one point of health, and he must reach and beat Topmaniac. See Topmaniac for more information on defeating this boss.
Purple Coins on the Battlerock
Mario will begin this level on the moving platform found in Battlerock Barrage. All of the purple coins are located on the path this platform takes, and Mario must collect them all while dodging cannonballs and electric walls. At the end of this path is a platform with a Gearmo. If Mario collected all one hundred purple coins, collect the Power Star; if not, talk to the Gearmo and Mario will inexplicably die.
Luigi under the Saucer
This Power Star is only accessible when Luigi sends Mario a letter with a picture of Battlerock Galaxy. It is a special mission found in Battlerock Barrage. Follow the instructions to get the Power Star in Battlerock Barrage. When Mario reaches the platform which normally holds the Power Star, it will not be there. Walk underneath the platform to discover the cage that holds Luigi. Lure a Bullet Bill over to this cage to free him, and he will give Mario a Green Power Star. Make sure to tell Princess Rosalina that Luigi found this one.
