Voodoo Vince: Remastered

To get this achievement you have to beat the final boss. To reach it you have to turn on the power by beating the Hall of Mirrors and the House of Awfully Scary Stuff. Once the power is on it will activate all of the rides. You have to hop on the ride with a bunch of spinning couches and jump to the next ride. Jump off the ride and you should reach the Ferris Wheel. Get on the Ferris Wheel and use the swing pin to swing to the next ride and continue to hop ride to ride until you make it to the giant ramp. The final boss starts when you hop on the motorcycle on the ramp.

IT IS VERY IMPORTANT
Make sure you get any collectibles before getting on the motorcycle. Once you do it you can't go back.

The Boss: It starts with you on the ground with a bumper car. You have to hit the buttons to raise the barriers. You have to hit the barriers with enough speed to hit the 3 targets. You have to avoid the giant robot to do it. Once the 3 targets are hit, the robot becomes immobile and you have to climb it using the door that opens on the side. You have to make your way up the robot and get into the jet left for you at the top. You won't die if you fall off as long as you don't fall into the black void. Fall damage doesn't exist. Once you get into the jet you have to shoot the very obvious target in the robot's mouth until it lets you inside. The jet controls can get annoying but it is doable. Once you hit the target enough times you have to fly your jet into the mouth to start the final section. The final section is a platforming challenge that tests everything you learned in the game so far. It is similar to the final part of Spongebob: The Battle For The Bikini Bottom except with a bigger focus on platforming than combat. You make it farther and farther up the robot and you have to make it to the brain. There are hazards along the path that do damage to the brain. When you reach the brain you have to use both triggers to do a special move to finish it off. When you do it a cutscene will play and you beat the game.

BE VERY CAREFUL
There is a chance for the final boss to glitch. There is a section where there are two sets of screws. There is a chance for the second set to get stuck in place making it impossible to reach. It happened to me. If this happens you have no other choice but to start a new game. It takes between 8-10 hours to 100% the game or 3-4 hours to rush through it.

ONE THING TO KNOW
If you get a game over before you get inside the robot's head you have to start the whole thing over from the bumper cars. Once you get inside you are safe.
