The Large Challenge Bundle appears in the store while a challenge is active. It costs 60,000 Power Credits and will grant 20 Challenge Credits.
Upon purchasing this pack, you'll get 20 Challenge Credits.
It is highly recommended that you do not purchase this bundle, as you can obtain 20 challenge credits easily through winning 14~40 single player battles (1 challenge credit earned per 2 energy bar used), which would also allow you to gain additional power credits instead of spending a lot of them.
Both this and the Small Challenge Bundle have been removed in the 2.11 update, as Challenge Credits are no longer needed in order to enter battle in Challenge Mode.
