Unfortunately, one can't say the same for Missile Defence, also from Anirog. This uses no fewer than seven keys, four of which are the cursor control keys - which in my experience are the worst possible choice. Positioned as they arc (it's rather like the old chestnut of rubbing your stomach and patting your head at the same time) everything gets out of sync and the game's over before you can shout "Nukes away". However, after a good deal of practice (assuming you have the patience) the poor old aliens who've come to attack your cities gradually begin finding themselves in a weaker and weaker position as your skill increases. No fewer than three fire buttons are provided to wipe out the monster meanies, before they either destroy you or disappear off the edge of the screen. It's all familiar stuff.
