There are 8 maps and four modes (Competitive, Duel, Escort, and Siege) for a total of 32 victories needed for this achievement. In Duel, Escort, and Siege modes, your partner can surrender to give you a victory. In Competitive mode however, you must combine to beat the AI. Set the victory conditions to 1000 points and 10 minutes, and work together as a team. Most of the competitive maps are quite easy to win, but some may require a bit of practice. Note that to win, you must beat the AI and end with the most points as shown on the victory map. Ranked or Private matches count toward this achievement.
