Play Survival mode and focus only on surviving. Go slow and do not worry about score, power-ups, or corn. This is not too difficult if going slow. You get plenty of lives. Which laboratory is the best? I find that the Military one is easiest, but it may just be personal preference. The obstacles seem easier to deal with and the power-downs are less devastating. This achievement can be gotten along with "Chicken is stronger than a cat!" as you should employ the same strategy for both. This achievement is also obtainable in a Survivor Global Weekly Challenge.
