Just want to say more tips:
Solider cant shoot you if he isn't forward to you.
You can get Speed Racer medal without buying upgrades and on first 3 stages of Great Escape.
Zombies can move in two directions only: left and right.They can't move forward at you.
Use handbrake to slow down the helicopter to make him hit the sign.
Anyway you made a nice guide!

Good guide! The only one I'm yet to get is flip flop. Good advice on getting it on police state though!
Also, Id like to add that you can tell which spikes are going to move by looking at the perception to see which spikes have soldiers at the side of the road next to them. These ones will move to the centre of the road. These soldiers will not shoot you.

Really? I thought those were the soldiers who planted the bombs. Thanks, m8, I'll update that.
