Now, if you're really good at this game, then you can probably get this achievement in any game mode. But if you're like me and kinda suck at it, I found the Team Objectives mode, Artifact Assault, to be a real easy way to get this. Each time you pick up the artifact, that's 150 points, returning it to your base is 500 points! So pair that with kills and stuns you'll probably be doing and a 9 minute match, this should be a decently easy way for you to get this. If you get at least the required amount of points for the achievement, it should pop up at the end of the match.
