Ragnarok M Eternal Love is in pre-registration on Google Play in Spain. But it is worth remembering that the game has already been released globally. Just like Epic Games, with Fortnite, Gravity didn't want to wait and has already made the APK available on the game's official website.
Description on Google Play:
Ragnarok M: Eternal Love is an open world MMORPG inspired by the legendary 2003 Ragnarok Online, inheriting the legacy of RO and attracting the attention of millions of fans around the world. Ragnarok M: Eternal Love brings Rune Midgard to life, reinterpreting the art style beloved by fans for over 15 years. The classic returns with a touch of modernity!
Remember to reserve a good space for the game. Ragnarok M Eternal Love is very heavy. Sometimes there is a bug in the game update and it consumes more than 4GB of space on your Android smartphone or tablet.
