Deadfall Adventures

You don't need to be in first place to get this achievement. It's based on your kill to death or K/D ratio. For example, a player who died twice after killing 10 enemy players would have a higher K/D ratio than one who died once after killing 3 enemy players. Depending on how the match goes you might not have to take out that many enemy players. You could get a few kills by approaching combat zones and then stay in safe places to reduce to the risk of death, which gives you a better chance at getting this achievement.
