Defense Grid The Awakening

I discovered this game via PA and both my wife and I have really enjoyed it and kind of sad we finished it (though it has a lot of variable gameplay types for replay).

I had not realised the tower defense map in War3 had spawned its own sub-reverse-rts game. I loved that map as well.

Can anyone recomend anything similiar? So a tower defense game of the same quality?

Thanks.

Someone hasn’t been paying attention in class…

Been enjoying this quite a bit lately. Good for getting the DoW2 multiplayer beta’s taste out of my mouth, went from no base building to nothing BUT base building.
