Yars Revenge Remake

Here we are again... I remember the original Yars Revenge well. It was an Atari 2600 console darling and had the most awesome cinema/TV advertisement Ive ever seen and one that I think still rates highly even today.
But what about the game? Thankfully it was as good as the advert. You took control of what can only be considered as a small fly (ok ok hi-tech spaceship, but it looks like a fly!). There is a big asteroid/disruption belt down the middle of the screen which you can hide in to avoid being shot.
To the right of this is the defence shield around the baddie youre trying to kill. So - shoot the shield away, hide in the rocks when needed and hopefully manage to defeat everyone. Just like the original though thats easier said than done.
