The discount on the Definitive Editions for owners of Dead Island and Dead Island Riptide will retire on Thursday, June 23, at 10 AM Pacific Time (that’s 6 PM BST in the UK, 7 PM CEST in Europe).
After the upgrade discount retires, any future discounts will still work but won’t be affected by whether or not you own the original games.
In the meantime, we are working with the developer on various fixes for an upcoming patch.
