South Korea-based game developed Gravity has kicked off the English CBT for Ragnarok: Spear of Odin for Android in Singapore. The beta will go on until 7 April 2017, so you have little over a week to try the game out for yourself.
Unlike its predecessor on the PC, Ragnarok: Spear of Odin takes the 3D hack ‘n’ slash approach, which is fitting for a mobile title as they tend to be less complex than a straight up MMORPG. However, that is not to say that the game is in anyway simple, as while there is lock-on, there is no auto-combat, so you still need to beat the over 200 monsters found in Ragnarok Online universe yourself. The game is entirely PVE, although there is a co-op mode where you and other three players will go on boss raids.
There are a number of job classes, which you can then branch off onto other paths once you reach a specific level, so there is some variety as to how you will be able play the game.
