• Pulse Cannon        30
• Firework Launcher 60
• Hover Gun            100
• Suck Mortar          150 

Purchase any of them and the achievement will unlock. Obviosly buying the cheapest is the quickest way to get the achievement.

There are three total movement upgrades for purchase.

• Performance Motor                  75
• Super Spring Jump System      75
• Super Mega Jump-Flip System 100

Purchase any of them and the achievement will unlock. Obviosly buying the cheapest is the quickest way to get the achievement.

You have to get all 500,000,000 points in one play through of the game. Since it would be near impossible without bonuses here are a few ways to increase your score.

• Play on the hardest difficulty "Master Technician"
• Collect upgradium while inside levels
• Finish levels quickly

The two armor upgrades are.

• Protective Armor        100
• Supreme Mega Armor 250

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."

Find all the upgradium means find ALL the upgradium. 

In order to collect all the upgradium you will need all the movement upgrades, the tractor beam, and the point to point lazer. I reccomend looking for all the upgradium after you've completed the game on Master Techinician difficulty and while trying to unlock the achievement "Master Technician" as it will add to your point total.

Upgradium can be hidden basically anywhere, so check and small ledges, dead ends, narrow passages, or large open areas. Remember that some of the scenery can be moved and might contain upgradium (like the crane in the first armory level.)

One of the harder achievements. Obviously set the difficulty to "Master Technician" when you're starting a new game and do not buy any upgrades as this will prevent you from getting the achievement (in case you thought you might be able to buy but not use them.)

Luckily you are allowed to use the upgrades you recieve from Karl and your starting weapon. This means you get to use the EMP rifle, the tractor beam, and the point to point beam. Since upgradium won't help you get through the levels you might as well try to rush through every level using the EMP's stun effect to prevent enemies from attacking you as you pass and the point to point beams ability to attach enemies to nearby scenery to slow them down and prevent them from chasing them and attacking you.

Of course you could always just go very slowly through the levels and try to use the EMP gun to kill everyone in your way but it seems to be much more difficult due to the weakness of the EMP gun.
