Dreadnought Galaxy

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

The Dreadnought is the ship that makes up most of the Dreadnought Galaxy, hence the name of the galaxy. It has cannons and spikes that can make Mario lose one Health Point. At the top of the Dreadnought, there is a pool of water. There are also Springs and Pull Stars littered all over. The levels on the Dreadnought Galaxy are much more challenging than it's similar counterpart, the Battlerock Galaxy.

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.

The entrance has three Astro 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.

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.

It is a medium-sized planet with a Bill Blaster and several Astro 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.

This planet has three parts. In the first part is a screw that moves forward or backwards depending on how much weight 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 Chomp Pups 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 Octopuses that need to be killed for a Launch Star to appear.

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 is a Power Star.

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.

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.

This planet has several cylinder structures sticking out. Mario has to knock two Spiky Topmen into an electrical barrier to free a trapped Luma. Then, the Luma will transform into a Sling Star that will lead Mario to the Cube Planet.

It is a small planet shaped like a cube. There is a Ground Pound switch that makes five blue Star Chips appear. A Spring Topman is also found here, as well as a Spiky Topman in the "Topman Tribe Speed Run" level. The player needs to use the Spring Topman to get one of the Star Chips here.

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. There are also Mines in the way that can be taken out with a Star Bit. Mario has to avoid the cannonballs while traveling by them.

A big, flat planet that looks like a zigzagging landing platform. It is blue, and there are several Spiked Sentry Beams that shoot electric waves at Mario. White circles around the Sentry Beams indicate how far out from the center the electric waves can go, and look like venn diagrams at some points where they intersect. Near the end of the platform is a Launch Star. There is also a Koopa Troopa on this planet. Its shell can be used to break open the treasure chests on the platform.

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 needs 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 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 Octopuses 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 Octopuses 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 on the Bob-omb and throw it, waiting on the platform for a few moments until he can get the treasure and/or the Launch Star.

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 Sentry Beam is making. When close enough, he can jump onto the the Sentry Beam, 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 (Speedy Comet)
When a Speedy Comet is in orbit, this mission is accessible. 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 (Purple Comet)
This level is access when a Purple Comet is in orbit. The player must collect 100 Purple Coins on the moving platforms from the end of Dreadnought's Colossal Cannons. Near the start, there is a Life Mushroom and a 1-Up Mushroom, which Mario can use them keep replenishing the lives he had. The only Star Bits on the level are along the wall where the cannons shoot. Unlike the "Purple Coins on the Battlerock" mission in Battlerock Galaxy, the platforms have no gravitational pull and the cannons shoot right at Mario. If on a non moving platform and have missed the moving one, another one will appear. The 100th coin is on the path of the launch star at the end.

Dreadnought's Garbage Dump
Like the similarly-named mission from the Battlerock Galaxy, Mario must blow up trash piles with Bob-ombs to get a star. However, here, there are more trash piles, and he has only 30 seconds.
