This achievement can be frustrating and will take a lot of luck and skill, first of all join a "Capture the Flag" gametype and take out your knife, this ensures that you don't fire any shots but now you need to be careful that you don't stab anyone. Just keep sneaking into your opponent's base and taking their flag back to yours, try to use different routes each time so that they don't keep killing you. It is also possible for this achievement to be boosted with a friend if you join the same player match. The achievement will unlock once the game ends.
