Follow the big gun path (the leftmost option), then pick the rocket launcher instead of the final upgrade.

I prefer [Canyon Defense](http://www.miniclip.com/games/canyon-defense/en/). Tip: don’t neglect to build walls; they’re useful as a means of funneling traffic to high coverage areas, and even more useful as gun platforms right in the path of every vehicle.

And good for making vehicles take a longer route, and even for providing building space for some more of the large improvements. Top tips spoilered: Multiple **Recyclers** are cumulative in effect - with a lot of them in play you can make an insane amount of money.  
Selling and re-buying a **Wall Factory** makes a section of wall available immediately. You only ever need two WFs at once to qualify for the **Laboratory** - otherwise you should have one or none.  
Doing the same with the **Nuclear Silo** makes a missile available at once.  
My best is somewhere round 280,000 IIRC.
