I love this game found at Nexon.net, which is a free online First Person Shooter, as far as I know, it is about 1GB in size with the normal game.
It is one of those games that require a patch check and it has a "Hackshield", but the three main computers i will play it on, I know the admin password. My computer, my family's computer and Grandpa's Computer.
Please, I think that anyone who likes either Combat Arms OR online FPS's would LOVE this portable app! Thanks in advance!!
It _IS_ Free, but I don't think it is Open Source, after all, it is a free online FPS!
