Just picked this on from Gamestation after some good review on IGN and good memories of TA the first time. It doesn't disappoint
Lots of huge battles (and I mean massive) with lasers and bombs flying everywhere. Not sure it's a massively tactical beast, a good rush with loads of units seems to do the job. Or you can just turtle up and build some awesomely big artillery The landscape does make a difference too, getting some missile bots on top of hill raining down fire on the enemy below is really good fun.
Worth checking out I reckon
