In the game this is kind of the central currency.

Things you buy for crystals:

  • credits
  • verdium
  • plane cards and brobot cards in Contraband Shop
  • evolve higher rank of planes and brobots (when you have collected enough cards)
  • level up 10 levels of planes at the time
  • use “Extra” when developing devices in Black Box (probability of a better item is improved)
  • Elite Containers
  • Planes can in most cases be bought either from crystals or credits.

Ways to earn crystals:

  • buy VIP – this will give you 300 crystals, and then 40 crystals per day for 30 days
  • buy crystals in Crystals Shop
  • heroic missions will earn you crystals
  • Daily Bonus will give you crystals on day 2, 6, 9, 13, 16, 20, 23 and 27.
  • In Broshop, each reset will give you on purchase of 12 or 20 crystals.
  • Each of the 5 levels in Assault will reward you some crystals. One entire run in Assault will give you 131 crystals.
  • Some Daily and Progress Quests give you crystals
