How to unlock the Rook blueprint in MW3 and Warzone

Season two is winding down in Modern Warfare 3 and Warzone, but there’s still one weekly reward left to earn.

Week eight’s reward is called Rook, and it’s not an Aftermarket Part or Conversion Kit like in previous weeks. But this item is needed as the final reward to unlock the highly anticipated Rotten Inferno weapon camo, which is season two’s awesome, animated seasonal camo.

Here’s everything to know about season two’s final weekly challenge unlock in MW3.
