How to unlock the Lock and load achievement in Spy Hunter - Definitive Guide
To fully upgrade a weapon, go to the upgrades sub-menu in the campaign menu. Fully upgrading a weapon will cost you roughly 7,000 research points. I would suggest you max out your machine guns first. They will be your most used weapon for the 1st third of the game.
