Christopher Buffa (Prima Games): Sailing the high seas is dangerous, even in a video game. Case in point, Assassin’s Creed 4: Black Flag, where all sorts of things can spell the end of Edward Kenway’s pirate career. Fortunately, you can turn the tide with AC4 cheats that you’ll unlock by completing specific Abstergo Challenges. Once unlocked, activate the desired cheat from the Pause menu using the Abstergo Challenges option. A word of warning: you cannot save while cheats remain active.
