To earn this achievement, you need to go to the "Ranked" section under "Multiplayer." Once this is done, find & select "Breakout." Here's how Breakout works:
-----------------------------------------------------------------------------------------------------------------------------------
Two teams of 4 players fight against each other, with each player having only 1 life every round.
To win rounds, players must either eliminate the enemy team or successfully deliver the flag to their stand.
In various parts of the map, there are spare weapons that can give you an advantage.
The first team to win 5 rounds is victorious.
The best part about this achievement is you do not need to win 5 games of it. Wins or losses still contribute towards your progress.
After you complete 5 games of Breakout, the achievement will unlock.
