You can choose between: Shaman, Hunter, Witchblade and Fighter classes. These classes subdivide into three more sub classes. Sadly, the classes are gender specific. The WItchblade and Shaman classes are female characters.
There's also "Artisan skills" in which aside from being let's say, a Shaman- you can choose to be a tailor, metalworker, an alchemist, and a cook. (I think I missed one)
After logging in, choosing your class you get to a screen that lets you:
Common game attributes
Aside those I mentioned, you could also change the hairstyle and customize it to a limited degree. You need to level up and in order to do so, you need to earn experience. This game though, as well as the other webzen games has a sense of 'story' in which you go through the game like an RPG.
Taking "RPG" up a notch
Most games I played before had quests up until you get to change your classes. But after that, you're on your own and all you do is basically grind (Grinding is a game term in which you go to dungeons repeatedly and gain huge amounts of experience)
C9 is very much like SUN online (figures because they're from the same publisher) with the quests running through the entire game. Until I guess you tire of it. You follow a story line and the NPC's start respecting you and the likes.
You don't need to click an NPC in order for it to talk. Interesting right? Sometimes they react to you and your current adventures just by you passing them by. I get the "Hey kuricurry, You should go talk to your trainer...and learn some new skills!"
I find it rather immersing. Most games get boring after a while. When you've reached a part of which there's no more changes and no more new skills. This one hasn't gone to that point yet. Seriously still addicted to it.
I like the fact that, when I move to bushes the leaves move as well. In other games you rarely see that kind of physics. There's also destructible objects and various traps in maps. It's also interesting that even the enemies get caught up in the traps and pitfalls.
There's also death caused by falling. Really interesting. There's also the power to actually jump forward, sidewards and backwards. Absolutely gorgeous movement as well!
Resurrection scrolls and Bosses
The game presents quests, and in these quests you are assigned to go to maps. What's interesting is that you're 'graded' as to how you perform and are rewarded appropriately. From D,C, B, and S.I don't think I've ever seen an "A" for a grade. There are also "Legends" and "Auspices". These are measures for deeds that you do in the game. A good example is, going through a map in 10 minutes-- It earns you a title of "In 10 Minutes" which I still can't see what it does. Auspices are a number of legends done. These can be selected and 'equipped'. These give you stats vital to all characters.
