Taste MY Foot Zombies...

Ahhh.... I love my Job..
The first thing you have to purchase in the shop is the Rock Pack.
Activate the rock pack as soon as you are begun as you will avoid the risk of hitting some spikes early on.
Do not waste your money on the chest bomb or nuke until you start earning over $6,000 per try. Instead of it, save for the 10,000 cannon and makes it your second purchase!
Purchase the guns in this order: Revolver, Uzi, AK-47 and Sniper Rifle. If you have the money, the Golden Gun would probably do wonders.
Always upgrade your cannon before everything else!
Once you get a better gun, try to keep the turtle in the air for as long as possible. There even are bonuses for not hitting the ground at all, so try doing that as often as possible early on in the game.
Although the WASD movement keys are mostly useless, keep pressing the D key all the time for some extra (possible) feet.
Best angle for the shot would be somewhere at around 50 degrees with full power.
