Step by step video guide on how to quickly farm 500 Bonus Cubes For basic text based instruction open the spoiler below:
*** Spoiler - click to reveal ***This challenge is on the Brick Challenges menu but you don't really need to highlight it unless you want to know how well your progressing.
I'd recommend a fast and wide car if possible, I mainly just used an X class Lego Senna
Now you need to go to the Airport leap danger sign, jump and collect all the bonus cubes on the runway and and the end of the runway.
While it is possible to keep going left and picking up a few extra cubes (around 9ish), it is faster to just keep running up and down the runway and Turing around quickly after each jump, thus farming 20 Bonus cubes faster over time than collecting 29 cubes at a slower rate.
I'm trying to make simple to follow achievement guides, so please don't just leave a negative vote, leave a comment explaining what you found difficult, or how this could be improved, so future guides can benefit
P.S. Sorry about the first negative vote, I forgot I had this as scheduled release and wasn't yet up
