In Super Mario Maker 2, the process of unlocking new course parts and features for your Course Maker is intricately tied to the game’s Story Mode. Here’s a detailed overview of how this system works:

Completing Story Mode Levels
– Story Mode Objective: In order to unlock new course creation options, players must engage in the over 100 unique levels of the Story Mode. Each level completed as Mario contributes to the rebuilding of Peach’s Castle, with players earning coins as a reward for their successful completions.
– Earning Coins: The coins collected from these levels are crucial, as they are used to pay Chief Toad for the construction of various parts of the castle. As you contribute coins to the reconstruction, new course parts become available for use in the Course Maker.

Unlocking Special Items and Costumes
– Builder-Themed Items: As you advance in the Story Mode, you’ll unlock special items, one being the Super Hammer, which is essential for creating certain types of levels. Additionally, progressing through Story Mode grants you access to exclusive builder-themed costumes for your Mii character, adding a personalized touch to your experience in the game.

Finishing All Story Mode Courses
– Red Flag Requirement: To unlock certain exclusive parts, such as the Robot Suit and its components, it’s necessary to complete all Story Mode courses using Mario specifically, and ensure that you clear the stages with the red flag. It’s important to note that using Luigi or relying on downloaded items will not contribute towards this requirement, emphasizing the need for dedicated play with Mario.

Gradual Unlocking of Items
– Progress-Based Unlocking: Not all items, course parts, and enemies are available from the very start. Some elements are tied to progression through Story Mode, meaning players might find certain parts—like Bowser or specific enemies—inaccessible initially. The availability of these components often correlates with the milestones you achieve in Story Mode.

Summary
In conclusion, unlocking new course parts and features in Super Mario Maker 2 revolves around completing levels in Story Mode, collecting coins, and investing them into rebuilding Peach’s Castle. This system not only enhances the course creation experience by gradually expanding the available tools but also serves to integrate gameplay elements that enrich the overall narrative and player engagement. As players dive deeper into the Story Mode, they see a fulfilling progression that encourages them to explore and create with newfound content.
