For easy brain stems all you have to do is stay on the very first level and keep killng people there until the cops come and then the military and finally comes the MIS. The MIS will give you 100 brains for each person but they are harder to kill than anyone else. BEWARE OF THE ROBOTS FOR THEY CAN SERIOUSLY HURT YOU!

In Destroy all humans you'ell find the local police, army, and magestic men to be both annoying and tiresome,but if you use Cryptos jetpack you can fly up into trees and stay there till they give up or you can snipe them. This also works on poles but not all of them.

First, go to the jetty (Dock) and get the farmer to notice you. DON'T KILL HIM!!! Then use your mind and put him on top of the house. Make sure he's on the side near the lake. Then take out your Zap-O'-Matic and shoot him like this (( =Attack -do nothing) =-=-=-=-=-=-=) He should go to the edge of the house and go, "Woooaaaahhhh! AAAAAAAAAHHHHHHHHHHGGGGGGG!" Then his neck will crack on the dock and will drown in the lake.

SPOILER ALERT(kinda)
When you finally meet the mutants made from furon dna, listen to them and read their minds.they will say funny things like"I will hug you, and pet you, and feed you, and call you george".

When you buy the pick up cars with mind upgrade you can use them as shields and bombs if you hit them enough. P.S. Use your imagination on what you could do with army trucks
