Pretty easy. All you need to do is surround the crystals with factories, upgrade them to refineries, and you're golden.
Use speed towers for your defense, with a few death beam towers ot keep snow at bay. Then you can just focus on slowing down your opponents with the Air Base and Gravity Well.
Awesome game! Better than the 1st (which is hard to do)
