Dreadnought Galaxy

The Dreadnought Galaxy is a galaxy in Super Mario Galaxy. This galaxy is a very mechanical and technological battle station. This is where Topmaniac is refought, the leader of the Topmen. It uses several elements from Battlerock Galaxy but is somewhat more difficult. It is based in and around a massive ship called The Dreadnought.

Beam Planet
It is a planet shaped like an hourglass that is full of electric beams and other electrical hazards that spin around it. At the end is a Launch Star that Mario must get to by jumping on a spring.

Dreadnought Main Core
The entrance has three Helmet Goombas and a Warp Pipe. The inside part is a side-scrolling area with hazards such as amps, cannons and moving walls. At the end is another Warp Pipe. The gravity of this area can be changed with a gravity arrow.

Tower
It's a section in the main planet consisting of various cylinders that fall when Mario gets to a higher level. On the top parts are a pair of moving walls and a Launch Star.

Aqua Planet
It is a medium-sized planet with a Bill Blaster and several Helmet Goombas. There is a vault that must be broken to flood the planet. There are also a lot of platforms with lasers that move across the water and a pair of Robot Turtles. Above it is a small cubical planetoid. Some metallic structures are above the water, and one of them has a Power Star.

Chain Chomp Planet
This planet has three parts. In the first part is a screw that moves forward or backwards depending on how much weigh it has on it. Beneath it is a green platform with Bob-ombs. The second part has several Flipswitches which Mario must press by avoiding the Chain Chomps that constantly fall from the dog shacks. If he presses them all, Mario can get to the third part. In this part are two more screws and two Electrogoombas that need to be killed for a Launch Star to appear.

Platform Path
This is a section on the side of the Main Dreadnought which consists of several platforms of different sizes that travel along a path. There are obstacles such as cannons and electric currents. At the end, after some upside-down platforms is a Power Star.

UFO Planet
This is a metal planet shaped like an UFO. In the upper part is a Green Topman and in the lower part is a Warp Pipe that leads to the Garbage Dump.

Garbage Dump
This is a planet shaped like half a sphere. It is inhabited by a Gearmo that cleans the garbage. There are also some Bob-ombs that Mario has to use to blow up the garbage to get a Power Star from the Gearmo.

Sphere Planet
This planet has several cylinder structures sticking out. Mario has to knocked two Spiky Topman into an electrical barrier to free a trapped Luma. Then the Luma will transform into a Sling Star that'll lead Mario to the Cube Planet.

Cube Planet
It is a small planet shaped like a cube. There is a Ground Pound switch that makes appear five Pull Star pieces appear. A Spring Topman is on here, as well as a Spiky Topman in 'Topman Tribe Speed Run'.

Artillery Walls
As the name says, these are two walls that face each other located in the Main Dreadnought. The cannons shoot Cannonballs, and there are Pull Stars in the middle. Mario has to avoid the cannonballs while traveling by them.

Landing Platform
It is a big, flat planet that looks like a landing platform. It is blue, and there are several obstacles that shoot electric waves at Mario. Near the end is a Launch Star. There is a Koopa Troopa on this planet. Its shell can be used to break open the treasure chests on the platform.

Topmen Planet
It is a planet shaped like an UFO. There are a lot of Spiky Topmen in it, and there are also many electric currents that block Mario's path. At the top is Topmaniac, waiting to be fought.

Infiltrating the Dreadnought
Mario or Luigi has to explore a couple of planets with lasers before he gets into the Dreadnought. Then he has to go through some sidesrolling areas before reaching a planet with a Bill Blaster. He need to flood the planet by breaking a cage with a Bullet Bill. This triggers laser platforms which he must jump across for a Power Star.

Dreadnought's Colossal Cannons
Mario will start out on a U-shaped platform with electric borders. Jumping down to the platform below, the player can get some Star Bits and also use a Bob-omb to break a cage with 1-Up Mushroom trapped in it. To get further in the level, Mario must run left on the giant screw until he's close enough to jump to the next platform. Here, the player must avoid Chomp Heads from hitting them while lighting up all the Flipswitches.

After this, two more screws must be traversed. However, the player cannot fall off like the last time, because there is a black hole beneath the area. This task is made slightly more harder, as two Electrogoombas will shoot Coconuts at Mario. If timed correctly, they can be destroyed when they first appear. Once the player is on the platform where the Electrogoomba's were, Mario can pick up the coins they leave behind. If Mario looks upwards, he can see Star Bits in the design of a Star. A Launch Star is up ahead. However, a Bob-omb sprouts from a device underneath it, making getting to the Star, and getting the treasure from the blocks near it (the left one has Star Bits, while the right one has Coins), time consuming. Mario can use his Spin the Bob-omb and throw it away from the him, but still on the platform for a few moments peace to accomplish getting the treasure and/or getting to the Launch Star.

Get the Star Bits that appear when the Launch Star is used. Mario soon lands on a small platform. This is much like the first mission of Battlerock Galaxy, except Mario doesn't have the leisure to go underneath the moving platform. Mario must dodge cannonballs, electric fences, and Goombas, while jumping to different platforms through use of gravity. Eventually, Mario will end up on a platform with a Thwomp that he must get past, which leads to more platforms. At the end of these platforms, Mario must jump to avoid shockwaves a Trampoline is making. When close enough, he can jump onto the the Trampoline, and get the Power Star.

Revenge of the Topman Tribe
Topmaniac has returned and brought the Topmen with him. The player must go across the galaxy fighting his minions, until they end up in an area where they must fight Topmaniac and his allies.

Topman Tribe Speed Run
Just like Revenge of the Topman Tribe, only with a 6-minute time limit, and more Spiky Topmen in the Cube planet and the UFO planet.

Battlestation's Purple Coins
The player must collect 100 Purple Coins on the moving platforms from the end of Dreadnought's Colossal Cannons. Miss only one and the player will lose a life. (Caution!:If the platform goes too far,you will be stuck and you have to wait for another platform to come along.Also in the " Dreadnought's Colossal Cannons mission" this happens if you wait too long so always move so you will not be stuck)

Dreadnought's Garbage Dump
Like the similarly-named mission from the Battlerock Galaxy, Mario must blow up trash with bombs to get a star. However, here there is more trash, and he has only 30 seconds. {Tip:Throw a bomb in the center of the dump.This takes out 5 piles instead of three)
