Step-By-Step Guide

1. Go to the Right to Activate the Switch
2. Continue Going Right to See the Main HDD Map
3. Proceed to the Red Button
4. Go to the Silver Block on the Right
5. Bring the Silver Block to the Blue Button
6. Go to the Objective and Exit the HDD

Go Right to Activate the Switch

Go to the right until you activate the red switch which will unlock a path directly to the south that can be a shortcut to skip the enemies to the right.

Once on the other side, you can still go left to get the purple box and fight the enemy if you want to.

Continue Going Right to See the Main HDD Map

Go to the furthest right of the map to activate another HDD Map where your current objective is located.

Proceed to the Red Button

Go to the top to press the red button after fighting the enemies and then going to the left to restore some HP. This will unlock a track in the middle which will come in handy later.

Go to the Silver Block on the Right to Unlock New Part of Map

Proceed to the Silver Block as this will unlock a new part of the map.

Bring the Silver Block to the Blue Button

Your goal here is to bring back the Silver Block to the blue button so the track's direction in the middle will be reversed, allowing you to access your objective.

Push the Silver Block to the middle of the new portion of the map and then go to the right side of the block to push it back on the direction of the blue button. In case you made a mistake, the green button on the rightmost side will reset the puzzle.

Go to the Objective and Exit the HDD

After switching the track's direction, go towards your objective which is the Lost W-Engine and collect the other rewards beside it. Press the red button afterwards to unlock new tracks towards the exit.
