Despite what the ONLY solution says (as of the date of this posting), you actually only need to complete the last rally point of each mission on co-op. You DO NOT need to complete WHOLE MISSION.

I ran through the game on easy first. Then, I did the last rally point of each mission on co-op. Achievement unlocked.

Don't you wish people would fact check their solutions before wasting hours of people's time?
