Yes.
No you can't play Combat Arms without downloading it but if you download the file then go to www.combatarms.nexon.net the sign in then you can play from your internet brouser.
It does not cost money to play combat arms, and you will never need to pay unless you chose to (for extra stuff).
Vindictus is an entirely separate game from Combat Arms, but it is operated by Nexon so it is free-to-play.
