I am looking for a First Person Shooter that allows my friends and I to create a private room. Of even allow one of us to host on out computer. It doesn't have to be a free game. My friends and I used to play Combat Arms, but now for some reason it will block one of us or we'll get kicked. All of us have formated our computers and have done everything we could to figure out the problem. We gave up, if it's not me not being able to log in, then it will be one of the others from our group. We are just looking for a decent FPS that will allow us all to play Free for all, and Co OP would be nice as well. Even an older game is fine as long as it runs on Windows 7. I was looking at Battle Field 2 but wasn't sure if it would run on windows 7 and didn't know if we could play together or not. Any suggestions would be much appreciated.
