Star Wars: The Force Unleashed II

As you progress through the game and fight enemies, you will get points which you can see by your health and power meters.

You push the back button to access your Force Powers screen.
Press A to upgrade a force power once you have enough points.

Upgrade it a third time to get this achievement. The force power I used the most in this game was Force Lightning so I upgraded that first.

I played through the game on medium for my second playthrough and had enough points to upgrade all force powers to level 3 half way through which is another achievement.
