Very interesting game, but there is an issue- translation, I mean like I know that Korea server is an active server, but sometimes it only says in Korean like in the 2 new' upgrade towers' in castle defense map, the towers' ability is written in Korean. So please add a language change option for everything.

This game is INCREDIBLE! You can play with others from all over the world (sorta) and it has so many different heros to play as! CDO Is the best game if you like to play RPG games. Upgrade diamonds to become stronger, Use items in the matches to become even stronger. There are 3 main game modes Defense is for diamonds, Boss raid is for relics and tokens, And Escape room is also for relics. So overall I will give this game a 4 star

Mechanic is so bad right now there is no item that benefits him I spend 5 hours trying to figure out how to build this guy (I have all the enchants) when I go hp and damage his skill damage drops to 0 when I try going auto attack (damage attack speed crit hp) build first his survivability issues came out and then his other skills (other than his mine robots) stops doing any damage going xp doesn't help either there isn't a relic that help with his issues level 15 defense is a torture with mechanic

Unbalanced game! Some hero can deal so much damage (multiple damage) to boss but single damage have limited. Stupid dev easily let ppl hack server and only buff certain hero thay they like. Not balance at all and not welcoming for new players. Waste of time game.

Can you put my account in to the American servers it makes me angry that my (angelius 2 rank) for mepdude2.0(my gamer tag) is not where I should be in the American servers, and I don't know Korean, so I'm left not being able to communicate with anyone? My phone also says that I can't download the American version because there was an issue retreating the game data so if you can help me please do, so I would give you 5 stars if you do :D
