In the first match stand in one place. Whenever Sark throws a disc shoot it down and if you are accurate enough you can do it with the first five discs thrown in a game. He usually throws a disc every four seconds.

For this achievement use the first match again. Move to the right side of the platform and Sark will throw a disc. As soon as he does, move to the left side of the platform. Rinse and repeat for sixty seconds and you will unlock the achievement. If things get bad, you can block, just don't throw a disc or get grazed.

Chasers are the pulsating orbs that follow you. Shoot down those and the orange ones with the spinning discs around them. Each green one requires two hits. Orange ones require three hits. Focus on this during a playthrough and you should not have any problems.

First of all, find somebody who owns the game. Plan to meet up and then take turns winning Speed Versus matches. Get five a piece and you are both winners!

First find somebody who has made it to the top of the online or offline leaderboard. Get together in a lag-filled (that is all of them), Co-op online match and rack up 50,000 points together. Achievement unlocked.

Make sure your settings are set to default (athough you can use the newer graphics). Stay alive, focus on incoming fire, and practice a lot to learn the levels. This is challenging but doable.

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.
