The closest game I can think of that is most like Combat Arms, is probably Halo Combat Evolved. (the trial version is free)
But I think Mac is very limited to free stuff.
there are tons of other free games like Gunz The Duel or Mabinogi or Combat Arms
AVA which is also Alliance of Valiant Arms you can find it at ava.ijji.com
No have has to be free, but there are other games like CrossFire that are free, like Soldier Front and AVA (by IJJI) And there's also another one called Combat Arms.
Not all games are bad for your computer,only some games are,combat arms is not bad for your computer.
Ventrilo is not in combat arms, it's a program where you can talk with people, often used for games / clans like battlefield and stuff like that.
No
It depends if you are downloading paid games or free games. Free games such as Combat Arms (exception Private Servers) are legitimate, while paid games like Counter-Strike is illegal unless you paid (not cracked).
Maplestory and Combat Arms Were both made by nexon so really they are both as good as each other depending on your likes in game genres if you like 2D RPG's then maplestory but if you like free FPS's then Combat Arms
Nexon.net offers Combat Arms for mac Counter Strike, but you must pay There is a game called Assault Cube which is free but underdeveloped.
Combat arms!
Combat arms for the pc, in my opinion it's very fun for a free online shooter
there is brave arms and offensiv combat
