You can get keys by selling foods at Space Burger.
So, how about CONVERTING scores and medals to key?
here are how it works.
- this feature is available at tier 99.
- this feature can be done at Heroes Academy Campus.
- Adding up ALL of your score and medals collected, you can earn keys, as many as your score and medals.
- your tier resets to 1, and your medal and score do to 0 too. so some missions become unavailable.
note: some types of medal like contents contribution, early access participation, and galaxy 100% exploration reward medal CANNOT BE SOLD.
- Don’t worry. your total play time, last connected time, your belongings DO NOT reset. ONLY MEDALS and SCORE reset.
