Maximum Effort Achievement
Defeat all tactical challenges in Raven Strike
If you've beaten the main campaign, chances are you know what to expect from the challenges. It's the same deal for this DLC, with most of the challenges involving the pistol and stealth kills, adding an extra bit of difficulty to the missions, especially on Expert. But, that's nothing a true Ghost should have a problem with. If you do have any problems, look HERE for my 100% tactical challenges guide.
