First of all...the description of how to get the achievement isn´t really precise. You are to complete the levels perfectly it says. Well...the most players think that this means everything has to be done in one run and without losing matches. You are allowed to do each of the 16 levels as often as you want or need. The achievement basically says that the way you complete each level has to be perfect but not the run itself. After you died by a suicide or got killed by the bot you have to let him win the round to restart it. That still sounds bad...I know that. But it is still WAY better than doing it in one run without dying once. However, I got a few tips for everybody (who is interessted) anyway:
1.Try not to get angry when you have to restart a level more than 20 times.
2.Take your time:the bots are really difficult to predict, but the are spots where waiting is possible.
3.Listen to music or do something relaxing
4.Make pauses when you are angry (although you shouldn´t, but I promise you will be). These can help you a lot.
