The way to win. Okay...do extreme mode on Lyne. Start out with a Rocket a little in front of half way of where the...thingies come out. Upgrade the rate twice. Then upgrade the damage to max. After that, make a Cannon within range of 1 turret. Upgrade the damage of that to max. Then, make 2 Tasers at the start of where the things come out. Upgrade the rate and damage to max. Then, add ANOTHER Cannon within 1 turret space of the rocket. Upgrade the damage to max. If you see a huge rocket, and it explodes, you've done it right. Wait till you get 1000 kills. Then you should see a 'turret' that increases damage. Keep placing as many as you can by the Rocket. By 1500, you should have at least 6 - 8. Thats your guide right there.
