This achievement will unlock the first time you upgrade a weapon fully. Each weapon has two distinct parts that you can upgrade, so that means the earliest you can get this achievement is at the game's second Power to the People station.

1. Neptune's Bounty - room after defeating Peach Wilkins
2. Arcadia - one of the rooms right before the Farmer's Market
