After some difficulty, I finally completed the last two Echo missions on Spec Ops - Armour Piercing and Wetwork. Armour Piercing was quite hard but nothing compared to other missions like Homeland Securty. Wetwork however was rather easy, that is if you are patient enough to withstand around ten minutes of cover. Overall Spec Ops was a joy to play - it was a thoroughly enjoyable and rewarding experience. I'm also now Level 64 on Modern Warfare 2, that is, thanks to some handy Riot Shield boosting with my Brother.
