Hi Im new to 2moons and i wanted to try it out but, i dont really dunno what to do can anyone help?

Just need to go arround killing everything.

Read guides on how to play 2moons if you are absolutely lost.

I would suggest you doing the quests reason is because it gives a lot of exp at low level or high. Reason 2 is the quest will lead you to another quest which will create a path for you at the same time it will make you walk around town showing you what NPC is what and where it is located. Hope this help.
