The final week of Season 2 in Modern Warfare 3 has begun and that means we get one final reward known as the Rook blueprint. Once the next season begins, there’s no going back to get it, so let’s get started on earning this HRM-9 gunsmith option.
How to Unlock the Rook Blueprint in MW3
Complete at least five of the Weekly Challenges in Week 8 of Season 2 for the Rook Blueprint as a reward. Five challenges can be completed across any of the major modes in MW3 or Warzone. So if you want to, it’s possible to complete three challenges in Multiplayer, one in Modern Warfare 3 Zombies, and one more in Warzone. This allows you to take on some of the easier challenges for each major mode when you run into a roadblock with progress.
