RoboBlitz

Set the difficulty to "Master Technician" and then play through the game. 

There are 18 levels in total that you must complete.

One friendly tip I can give is to collect as much upgradium as possible and not worry about score for the time being. With upgradium you can make your Robo much more powerful and the game won't be very difficult.

You can always go back to previous levels and get a better score on them for the achievement "Master Technician."
