Back 4 Blood looks like a solid co-op zombie shoot ‘em up, Left-4-Dead-creators Turtle Rock Studios obviously know what they’re doing in this genre, but what really sets the game apart? The latest Back 4 Blood trailer attempts to answer that question, detailing the game’s “Game Director” AI that adapts levels on the fly, and the Card System that will further alter the challenges you’ll face and your character builds. You can check it all out, below.

　　Looking promising! The Game Director concept is cool, provided it works as advertised, but I’m a bit cautious about the Card System as it feels like it might be Trojan horse for microtransactions. Here’s a bit more official detail about the two systems…

　　Back 4 Blood takes advantage of an adaptive A.I. known as the Game Director, which works behind-the-scenes monitoring the actions, health, and choices of players. It responds accordingly by changing environmental conditions, adding obstacles, and unleashing special Ridden mutations through Card System modifiers known as Corruption Cards. Players can change up the gameplay by utilizing specific cards to strategize against the Game Director, from amplifying equipment to reloading weapons, as they take on hordes of enemies in their path.
