Left 4 Dead 2 Cheats :
Code - Easy way to get The Real Deal achievement
THE REAL DEAL-35G-: Survive a campaign on Expert skill with Realism mode enabled.
First, have one of your friends play a campaign, (preferably Dead Center), on Easy Realism. On the final chapter, as the rescue vehicle appears, have them change the difficulty to Expert. Then YOU join the game and simply get to the vehicle. Your friend needs to survive for about 30 seconds after he changes the difficulty, which is really the only hard part.
