Ragnarok Infinite Gamemode
One of the main highlights of the update is the Ragnarok Infinite gamemode. Players can access it from the Events tab or the lobby. In this mode, you are given a preset team of units instead of your normal lineup. As you progress through waves, your units become stronger and you earn God Coins, which can be used in the event shop. This mode also gives players a chance to obtain the Secret Unit: First Emperor.
Ragnarok Team Event Infinite
After the Ragnarok Live Event ends, a portal will appear in the middle of the map. Entering it will start the Ragnarok Team Event Infinite. During this event, players earn points for their chosen team. These points increase as you survive more waves, and you can also unlock an exclusive title.
Olympus Judgement Challenge
Another new mode added in Update 1.5 is the Olympus Judgement Challenge. This stage can be accessed from the Challenge area and gives players a chance to obtain the Secret Unit: First Human. It is designed as a difficult challenge mode, so strong units and proper strategy are recommended.
