Well,as far as taking over places with your guild is not sure yet.They do have some kind of taking over parts of land in the korean version but still nothing special I believe(not sure).Yeah it will mostly be grind and quests.
Leveling up as well but thanks to the good graphics and gore it is enjoyable to grind and do quests.Ofcourse there is more to do than just grind and do quests.You can Mix your DNA which is a big part of the game and also the beast possession system isnt shabby.But thanks to the game being in closed beta we dont know any facts for sure.
Atleast not yet.The Korean version of the game has alot more to do than just grind like taking over other guilds and a huge guild fight (98 vs 98) is allways fun.There is also a bloodbath match that is (4 vs 4)Which is for the four best in each guild.
But to get back to you original question?
Will it be mostly grind and leveling?The answer to that is Probably.I think there wont be anything more added than there is right now .In terms of new modes or anything.But the taking over parts of other guild territory will be added I guess because it is in the korean and the russian version.The Killing and leveling is mostly a big part is a F2P game because its free.And thanks to if they will add cash shop ofcourse they will also make new stuff.But try it out when the open beta begins.You might be suprised because they havnt managed to fix all the bugs and havnt added all the content.Altough I will repost If I will find something out about the features and Grinding.
