Secret Weapon asks you to distract 10 soldiers with Chorizo, the dachshund Amigo in the wheelchair. His Attention-Seeker ability pulls soldiers away from their posts.
1. Set Chorizo as your active Amigo. 2. Find a group of FND soldiers who have not spotted you. 3. Send Chorizo toward them so he draws their attention. 4. Repeat until ten soldiers have been distracted.
Use him at checkpoints: while soldiers watch Chorizo, you sneak in for takedowns. It counts over time, so you will get it by using him as your stealth Amigo for a while.
