ORBIT

To unlock the "Tech Boy" achievement you must upgrade all three of the SHIP SPECIFIC powers. You do not need to upgrade the common powers (cannon, system, engines).

The required skills to upgrade are:
- SHIELDS
- WARP
- BALLISTA

The fastest way to upgrade each system is to fully upgrade one at a time (they will appear to be reset after each full game, but they are tracked on the achievement tracker). I would suggest playing the following game loadout as I found it to be the fastest:

- choose FORGE
- choose 4 ROUNDS
- select ANNIHILATE (on first bar)
- select TOURNAMENT (on second bar)
- press "X"
- set Orbits (-)
- set Size (+)
- set Speed (+)
- set Gravity (-)

Start the game and select the appropriate ship type to access the SHIP SPECIFIC power.

Using your 2nd controller, dive the 2nd player into the circle or orbits to kill them. After five (5) deaths and the round is over.

Upgrade the SHIP SPECIFIC power in between rounds. Repeat with the remaining other ship types to unlock.

The are 5 columns of upgrades;
Cannon
System
Engines
Shield
Warp
NOTE: You get 4 at a time; Shield and Warp alternates between games.
Each of them have 3 locked items.
All you have to do is unlock each...and it's cumulative.
Go to forge, any mode (I used Destroy and Tournament), 4 rounds and set attributes to (-) by pressing "X". After each round the upgrade menu comes...upgrade and start the next match. I advise you upgrade one whole column at a time to keep track. After upgrading the last column after multiple plays, achievement pops. Enjoy.

EDIT: Priest Crow suggests "each ship has it's own unique upgrade" so select and play with all ships just incase and especially if the achievement counter gets stuck.
