'Friendly Fire' game on Android

OK, so this is the addictive Android game I mentioned last time I 'talked' about my new Android phone... Naturally it's a free game (otherwise why would I be playing it?) although they do try to get you to pay to upgrade, obviously that didn't work on me, but I suspect others have been cajoled into paying out to get quicker results from the game...

It's a military base-building game with a twist - the twist is that it adapts the actual location of your home as the location for your base - it uses google maps for it's basic layout and then overlays the playing 'board' where the action takes place - so you end up defending your own street which is a very neat twist... Difficult to explain it further without trying it for yourself..
The gameplay is familiar, you build up your defences, and some attacking forces then attack other bases - you can choose to attack people in your own locality, your own country or attack others all over the world. I started this game with a few friends at work and you can attack each others' bases when they are in the same locality which again is another nice twist. I was told it would be addictive, and it lives up to it's billing...
You will be attacked from time to time, but a successful attack means you are immune from further attacks for 12 hours (or until you decide to attack someone else), and although your base is instantly rebuilt, you may lose 'resources' and 'rank' as a result.
As you progress through the levels, you build better defences and better weapons - it's a simple enough concept and much-used, but this has some nice touches which makes it a real addictive pleasure.
