"Apex Hero" launched a new campaign called "Iron Crown Collection" from August 13 to August 27, which was supposed to be the most anticipated event for players. However, due to Krypton problems in the campaign, many players began to complain, and the number of complaints was increasing. Fortunately, however, after realizing the seriousness of the krypton problem, officials began to repair it. There are two main problems of krypton gold in "Iron Crown Collection". One is that the price of krypton gold in the game is too high. The other is that the krypton gold war chest in the game can only pass through the task liver to two out of 24, and the task requirements are very harsh. The rest can only spend money to draw. After learning about the problem, Renaissance Entertainment first expressed its apology, and then announced that the event will start on August 20, adding 12 legendary items to the store. Players can buy one of the 12 items for 1800 game dollars, of course, if they want to buy the Iron Crown Apex package.
