The hardest achievement in this (or arguably any arcade) game. Not only do you have to beat that 50,000 mark, but you need to do it again without dying and then score an additional 10,000. Good luck.
Thanks to Ank 1 for some additional strategies:
- Do it online, the lag makes it easier.
- Do it on level three, you get more points, and you have three platforms to move around on.
- Don't just keep randomly firing, you will kill Sark by accident and advance to the next level if you kill him twice.
- Normal discs should not be a problem to avoid, you should only shoot if you are certain that you are going to hit it, otherwise just dodge them.
- The green objects he throws are worth 600 points each and he throws two at a time. This is where you can get the majority of your points.
- When he throws one of the super spinners (the ones that home in) stand at the back of the platform, if you ca not kill it before it gets near you run to the front of the platform then jump to the other platforms, then kill it.
