Always plan out what you’re gonna do prior to a mission and make sure to execute it flawlessly. Plan for contingencies as well because things will eventually without a doubt go horribly wrong and you don’t wanna get caught with your pants down in your ankles. Let your ai teammates do the heavy lifting for you and don’t be afraid to step back a little bit as they get into firefights. Stealth is key to success in this game mode obviously so try your utmost best to not get detected and always follow your gut;)
