Hello Everyone,I am Spacers and I am  gonna tell you a another Promo code that is released recently.Firstly Thanks to my Friend BLOO for telling me the code.Now Just see the steps to get the code:
Open your map that is located at the right hand side of the screen.
Now map will open up on the screen and then click on Space Hero Academy.
After reaching there go inside the Academy.
When you will go inside it you will see a promo code machine you have to click on it.
After clicking on it type the code MANIA12 in it and click on send code button.
After clicking the button you will get a message.
After this message they will show you the goodies you have unlocked.
