Destroy All Humans Hints

To gain additional DNA from Brain Extractions, complete all of the main missions.

Example: Instead of gaining 10 DNA, you will gain 15 DNA.

If you want to make the humans clumsy on destroy all humans 1 or 2 [which ever one you have] just target a human and tap the triangle button once. if you hold it down to long it will make them lift off the ground and you might get found out. but if you tap it they fall straight to the ground.

When you land you have to turn around. you should be facing away from science town. if you are go straight to the hill in front of you. go over the hill and there is the yeti!
