Basically season 5 will start February 4th and end May 30th. Aquaman will be available on the first tier of the BP and Lola Bunny will be a daily log in reward. After May 30th the game will go to offline only, but you must download the game AND log in to it BEFORE then because it will be removed from digital storefronts afterwards. No more real money purchases from today onwards, but you can still use any Gleamium etc. you already have.
