First Impressions: Defense Grid: The Awakening

This is another game which featured a special achievement for a Steam Summer Camp giveaway entry. It's on sale today, however I actually bought it a while ago (in the last sale I think) but never got around to playing it until now. It is a tower defense type game so the main concept is not really original but it turns out it's a really good implementation. The graphics are nice and there is an excellent selection of turret types and maps to choose from, the controls are simple and most importantly it is fun. This is one I will definately be playing more in the future.
