Steel Defence Commander

From the author of Cat Death Auto (and, it goes almost without saying, the slightly less interactive Badger Badger Badger Badger - Mushroom Mushroom) comes a new slant on an old genre - the old genre being the vertically scrolling shoot-'em-up, and the new slant being: you control the ground and air forces that are being shot at so enthusiastically.

On the plus side, it's not like you don't have any weapons of your own, from tanks, mines and gun turrets to waves of fighters whooshing down the screen. It's fairly easy to beat on "Easy" once you get your head round the idea, but then there's three other difficulty levels (plus a clever 2-player mode).
