EA Community Manager confirms decision
On May 31st, EA announced in the Need for Speed subreddit, the digital storefront removal of the following titles: Need of Speed Carbon, Undercover, Shift, Shift 2: Unleashed and The Run has gone ahead.
Players will not be able to purchase them anymore and all in-game stores are closed.
The decision was made to prepare for the shutdown of each game’s online services on August 31st. This means online races will be available in the meantime until the aforementioned August date arrives.
From September onwards, only the offline features will continue to be accessible for the games.
