A Startling Metamorphosis Achievement
A Startling Metamorphosis20
Transform from Lou Ferrigno to Hulk (Lou Ferrigno)
To unlock Lou Ferrigno, you must complete the four missions he gives you in Manhattan. Refer to the video below for those missions.
When you’ve completed all four missions, you can purchase him for 10,000 studs. Once you’ve done that, hold to bring up the character grid (if you can’t do this yet, visit a blue or red platform) and select Lou Ferrigno. Hold to “transform” into the Hulk, and the achievement will unlock shortly after.
