Don’t worry about spending the in-game currency. Each time the game is patched during closed beta, you’ll be reimbursed. This will end after one final reimbursement at the start of open beta, so don’t get too spend-happy
The Founders Program "Credits" and "In Game Currency / MC" are ready for you to spend at will.
Important: You will be refunded the entire amount each time we patch the game during Closed Beta & once again when we commence the Open Beta.
Additionally, the update also announced that the Founder's program has been extended beyond today and provides a few additional details about what needs to happen before moving to open beta and what players can expect during the closed beta. Head over and check it out for all the details.
