Dreadnought Galaxy
It has been requested that this article be rewritten and expanded to include more information.
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 Topman. It uses several elements from Battlerock Galaxy but is somewhat more difficult. It also has a massive ship called The Dreadnought.
Known Levels
Infiltrating the Dreadnought
Mario (or his brother) 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 lead/throw a Bom-omb to break a cage holding a 1-Up Mushroom. 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 Chain Chomp balls from hitting them while lighting up all the blue tiles.
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 Electrogoomba's will shoot coconuts at Mario. If timed correctly, they can be destroyed when they first appear. Once on the platform where the Electrogoomba's had been, Mario can (if he was fast enough) pick up the coins they leave behind. Mario should look upwards to see Star Bits in the design of, ironically, a Star; Mario can get these by pointing at them with the Wii Remote. A Launch Star is up ahead. However, a Bom-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 Starspin the Bom-omb and throw it away from the player, 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, except Mario doesn't have the leisure to go underneath the moving platform. Mario must dodge cannonballs, electric fences, Goomba's, and jumping to different platforms through use of gravity. Eventually, the 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 waves a Jumper is making. When close enough, he can jump onto the the Jumper, and get the Star.
Revenge of the Topman Tribe
Topmaniac has returned and brought the Topmen with him! You must go across the galaxy fighting his minions, until you fight him in an arena.
Topman Tribe Speed Run
Just like Revenge of the Topman tribe, only with a time limit.
Battlestation's Purple Coins
You must collect Purple Coins on the moving platforms from the end of Dreadnought's Colossal Cannons. Miss only one and you lose a life.
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.
