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 fought here for the first time.

Starting Planets
These planets are a bunch of saucers near each other. In the first mission, Battlerock Barrage, there are five Blue Star Chips that Mario must collect to create Pull Stars to lead to a Launch Star, which takes the player to the Moving Saucer Planet. There is a ? Coin that will create several coins here. In the second mission, Breaking into the Battlerock, there will be barriers that must be destroyed by Bob-ombs that come out of the dispensers. One barrier contains a Launch Star, which will take Mario to the Molecule Planet. In the third mission, Topmaniac and the Topman Tribe, Mario must ride some of these saucers to a Launch Star, which will take the player to the Metal Bowl Planet. However, these saucer groups are in different places on Battlerock.

Moving Saucer Planet
To get this planet to move, Mario must spin the bolt on the Saucer. This Planet takes Mario through an area filled with cannons and some barriers. This Planet has a few electrical barriers on its side. Mario can collect a ? coin that will make Star Bits come out of two cannons. At the end of this Planet are the Big Saucer Planets.

Big Saucer Planets
There are two huge saucers here, each with some barriers that can only be broken by Bullet Bills, which are fired near the second big saucer. The Power Star is contained inside one of these barriers. On the Seventh mission, Luigi will be trapped under one of these barriers, which have some poles next to the barrier, making it harder for the Bullet Bills to break the barrier. When Luigi is rescued, Mario will get a Green Power Star.

Molecule Planet
This Planet is shaped like a molecule, and it has Incoming Chomps moving all around it. There are Bob-ombs here that will destroy a barrier containing a Rainbow Star and a Luma. The Luma will take Mario to a spiky area, which has a Launch Star that goes to the Battlerock Planet. There is also a Hungry Luma that, when fed thirty Star Bits, will create a Launch Star to the Garbage Planet.

Battlerock Planet
This Planet is a giant rock with metal inside. Inside, Mario must use a Bob-Omb to destroy the barrier to the cannon. The player should then enter the cannon and aim for the Luma to free it, which could take two or three times (one if the player is experienced). When the Luma is freed, Mario can access a Launch Star to the Missile Planet.

Missile Planet
This Planet is shaped like a missile. Mario will have to bring a Bob-Omb to the cannon on the other side of the Planet, avoiding the electrical barriers. Then, the player must enter the cannnon and aim carfully past the moving pieces of metal, so Mario can reach the Power Star. If the player misses, Mario will fall back to the planet.

Garbage Planet
This Planet is filled with trash. If Mario talks to the Gearmo and blows up all the trash with Bob-Ombs in the allotted time, the Gearmo will give Mario a Power Star.

Metal Bowl Planet
This planet is a bowl made out of metal. Here, Mario must Spin a Spiked Topman in to an electrical barrier, thereby breaking the barrier, and freeing a trapped Luma. The Luma will create a Launch Star to the Gravity Planet.

Gravity Planet
Mario should enter a pipe which takes him to an area where the gravity changes by Spinning some arrows. Mario will have to go through a series of moving platforms before entering a pipe to the Barrier Planet.

Barrier Planet
This planet has a Sling Star, which takes Mario to an area with Spiked Topmen, which the player must Spin them both into a barrier, thus disabling the barrier itself and taking Mario to a Launch Star, which will take the Player to the Topman Planet.

Topman Planet
This planet is where Topmaniac is fought. It is filled with electrical barriers all over it. There are also some Spiked Topmen and Mini-Topman here. When Topmaniac is defeated, he will give up a Power Star.

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. After the player collects the Star Chips will cause a set of Pull Stars to form a path that leads Mario to a Launch Star. Mario will land on another small platform and must bounce on an enemy to reach a higher platform. The player will have to Spin on a blue screw on this platform to make it move. Mario will have to dodge the cannon blasts and electric walls as the platform moves, and Mario could run 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 Power Star.

Breaking into the Battlerock
Mario begins this level on the same set of small platforms. One platform contains a never ending 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. The player will have to use the Bob-ombs to break open the Luma's cage, and the Luma will transform into a Sling Star. This will sling Mario into a Launch Star, which sends him into a Pull Star minefield. The player will have to 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. Mario will have to use a Bob-omb to free the cannon. Then the player should jump into the cannon, and Mario will have to aim for the moving glass chunk. The player will have to hit it two times, which 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. The player will have to free the cannon and jump in. The Power Star is circled by moving platforms, so Mario will have to 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. Mario will use the Pull Stars to reach another platform, then he shall use the Sling Star to reach a moving platform. This platform moves through a minefield, so the player will have to 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. Mario will have to 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. The player will have to Spin next to the arrow to reverse gravity and go right while dodging the firebars and carefully navigating the spinning platforms above the lava. Mario will have to Spin next to the the arrow to flip gravity again and start moving right. The player shouldn'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. Mario will have to fall upwards through the gap and run right while dodging the crushers. Next, the player needs to bounce on the trampoline to reach a Warp Pipe, and then 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. Mario will have to 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. The player will have to ignore the Topmen and Mario needs to walk to the topside of the platform where a Luma Shop and Topmaniac awaits. After defeating Topmaniac, the player will earn a Star.

Battlerock's Garbage Dump
This is a hidden Power Star found on "Breaking into Battlerock". Mario will have proceed as normal, but when Mario reaches the planet full of Chomps, the player shouldn't free the Luma in a cage. The player will have to talk to a nearby Hungry Luma. Mario will need to 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 Mario will have to make sure they are placed well and that each one takes out three or four pieces of garbage. There are yellow circles on the ground which indicate the best positions for the bombs to be placed. The Gearmo will give Mario 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 with Topmaniac. He will only have one point of health, and he must reach and defeat Topmaniac. Once again when defeated, he will give a Power Star.

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, the player will have to talk to the Gearmo, the player will get a Power Star; if not, Mario will inexplicably lose a life.

Enemies
None.

Luigi under the Saucer
This Power Star is only accessible at first when Luigi sends Mario a letter with a picture of the Battlerock Galaxy. When Mario reaches the platform which normally holds the Power Star, it will not be there. The player needs to walk underneath the platform to discover a cage that is holding Luigi. Mario will have to lure a Bullet Bill over to this cage to free him, and he will give Mario a Green Power Star.
