And I stopped playing it 2 days ago after getting to this snowy area. The disc was working fine, no scratchs I could tell because I hadn't even taken it OUT of the system yet. The system hasn't moved, been turned on, or even looked at for the Past 2 days. Now I'm playing the game again, except now, I can't hear gunshots or any weapons-related noise, and its pissing me off.
If anyone has experienced a similar problem with this game or any other game that's an FPS and/or found a solution, please share, I need a way to fix this because this copy isn't mine, it's my brother's.
