Complete any mission in Counter-Operative Mode.



This requires you to take the role of the agent (joanna) and complete all chapters of a mission without dying/being killed by the counter-op player. (completing all appropriate objectives on the way)

Most easily done on the third mission Chicago - it consists of only one mission and is simple to complete.

your counter-op player can be one of three people: (though the first option is easiest)
- A second local controller (sign in a guest and let them stand still)
- An xbox friend (select private match, invite, and ask them not to kill you)
- A randomer over xbox live quick game, though for this you need to invite them into the party and ask them to let you win.

The counter-op player can take suicide pills to kill himself or kill other AI enemies to speed the process

achievement unlocks upon completion of the last chapter
