UPDATE: GAME has confirmed that all pre-orders of Fallout 4's Pip-Boy Edition are safe, and that all orders will "receive an update on their order via email in the next 48 hours."

"Thank you for your patience, your Pip-Boy Edition order is still reserved and will not be released for general sale."

The retailer has yet to clarify why cancellation emails were sent to customers earlier today.

ORIGINAL STORY: Oh dear. Just days ahead of Fallout 4's launch, UK retailer GAME is reported to have unexpectedly cancelled orders of the game's highly-anticipated Pip-Boy Edition.

The £99.99 edition, which includes a replica model of the game's Pip-Boy, is due to launch in the UK next Tuesday. But in an email sent to some customers this morning, the retailer said that it had "hit a few issues" when processing their order, citing problems with payment being taken from the customer's bank or PayPal account.

"What this means is that we cannot collect payment or ship your order right now," the email said. "Please contact Customer Service on 0208 827 0099 and we will re-place your order for you."
