Am I the only one to realize that the only logical way for the Tripod to gain money for killing these humans is that after the level, he collects the remains of the people and vehicles and sells them on the Alien Black Market?
Also: "Sir, our RPGs and Tanks seems to be doing much more damage to this thing than our rifles and Hummers. Should we use our resources to build AA Tanks?" "Ridiculous suggestion Sergeant, it's only been a couple days. Just send more SUVs and foot soldiers, with a few regular tanks and helicopters!" -On the 5th day- "Sergeant, send out those AA Tanks now, but only a couple. It's only the 5th day of this invasion, after all. We mustn't be too hasty."
Fun game, and the easy badge was actually pretty easy for me. But the only way to get the hard badge without totally losing your mind is definitely to use the Right-Click, Play trick after 2 launches on the first level until you can buy everything.
The way I did it was to aim almost completely horizontally, fire with full power, and then use Freak-Thrust 3 times in a row and then the skis. Ended up at 7500 and am saying goodbye to this potentially fun, if all of the issues were fixed, game.
Good luck to everyone else.
