So I recently repurhchased Call of Duty 4, for nostalgic purposes, and I heard things about the servers being utter trash now due to hackers and such. I put the game in and started an online match and I still haven't came across a hacker. My best guess is that people just stopped caring enough to hack and have moved onto other COD's. Which is great for this community because people are still playing this game! I don't have a problem finding a match, even though it's nothing like it use to be a few years ago, I still get some nostalgic pleasure. Purchase it again, I highly suggest you do!
