Don't even bother with the tree until you have almost all the other upgrades. Max out the Research Skillpoints first (you should be able to do this just as Wave 2 comes). Then put a few points into armor and regeneration to keep yourself alive, and start to max out accuracy, money, and reloading evenly. Buy the handgun, then the machine pistol, then just save up and buy the minigun - if you upgrade money quickly you should have the minigun by wave 10 or 11. No need to max out armor/regeneration if you're not dying. When you have 11 skillpoints, max the tree growing skill, and it should only take 2 or 3 waves to grow the tree fully. Make sure you have the minigun before you do this. I beat the game in just over 3 days (wave 12) this way.
Another decent game, but hardly any variation from the first two. Also, too much luck involved. Either map out specific paths for the guards, or remove all ingame achievements so people don't waste their time. I sure didn't.
