I downloaded the demo for this game and it was half life 2 episode 2 (i think) and it said it was rated teen. It didn't seem to bad, no one ever cursed but there were a lot of bloody zombies. I checked back online and it said it was rated M. Is it just team fortress 2 that is rated M? This game is discounted for 20 dollars at gamestop and I may get it. I just need to know how bad team fortress 2 is and what the characters say in half life.
