K.O.S – Secret Operations is a free-to-play MMO first person shooter for PC. It is a good example of its genre and includes some interesting features to complement the polished gameplay. The low system requirements allow virtually any PC to run the game.

There are four game modes to choose from and the player is able to choose his character from about a dozen of soldiers. Each character has his/her own advantages, such as increased damage bonus for the Green Berets. This assures that there is some strategy involved, since a particular advantage may be more fitting to one player than the other.

The ranking system, both for a single player and for clans allows everybody to check their qualities and compare themselves with the rest of the world. The game includes Xfire, enabling players to communicate between themselves through voice chat, among other possibilities.

YNK Interactive also publishes Rohan: Blood Feud and Seal Online.

K.O.S. Secret Operations system requirements:

OS: Windows XP / Vista
RAM: 512 MB of RAM | HDD: 1.5GB Free
CPU: P3 800 MHz
Graphics Card: GeForce4 MX

    • QuaziMotorola on May 5, 2013

      MM is the month (like 03 for march), DD is the day (like 05 for the fifth day), and YY is the last two numbers of the year you were born in (say, for 1984, you would put 84).

  69. 3kekoi on September 25, 2012

    i love thes game!!

  70. jhonnery123 on September 25, 2012

    gusto kho mag aim bot pwedi??

  71. veltrix on August 14, 2012

    this game is pretty good, i dunno why ppl pwns it with their commentaries. My pc isnt good enough to run A.V.A. or Genesis A.D. or Ghost Recon or any of those uber advanced games. I feel my time and internet bandwidth was worth the download.

  72. xxmiku on July 18, 2012

    ok ignore my post from march 25 YNK fixed the problem and made it easy now you can easily start the game by clicking on the icon.

    anyways i love the game because of the music, the weapons, the awesome character customizations, way how you can fight other people from other countries, the maps, the AI bot option, alot of stuff is cool about this game besides this game is damn addicting @_@

  73. xxmiku on July 17, 2012

    i actually love this game i dont know what everyones problem is with this game :/
