Did you try the search function? By 75 posts, I would have thought that you would know how to use it by now.

Unlimited lives + free towers + starting money + using combinations = win.

Using the Blue blue green red red with blue hitting first combo and using loads of them works very well, also blue blue yellow with blue hitting first or blue red yellow with blue hitting first are both good for tight places. Using that tower that lets you hit closer is VERY useful as well so that as soon as they enemy comes on the screen BAM a dozen mines go onto the playing field, and when you get near the end and you're getting close to the score limit the mines come in very useful.

OR use the green line combo. Basically you just pump greens onto the playing field and it makes one massive chain.

How in the world do I give Karma? Because I would've given it to pythag, even though I already have all the badges.

you have to have at least x posts, i'm guessing x = 10 posts.

Even better. The ultimate hack that everybody has been waiting for.

Here's the hack for a one-hit kill. What it does is NOP out the code that checks if energy is less than zero, so then it goes straight to the destroy function.

Now, for strategy to use with this: First, get 2 blue turrets, and upgrade their rates whenever possible. At this point, you can send maybe 3-5 waves at a time. After maxing them out, add a couple more blue turrets and max out those rates. Eventually, you should be able to send in maybe 10-20 rates, no problem.
Now, the next thing you want is the fusion gun. Why? because it pretty much fires in a straight line, knocking down anything in its path. So get one (or two) of these, max out its rate, and now the enemies will be stopped at the beginning of the screen, no matter how many waves you send in. Enjoy!

Oh, and one more thing. Be sure to watch your kills and such so that you don't end up on the high scores. Looking at it right now, there are definitely some outliers who are obvious hackers.
