Use only the EMF Visualizer to complete Ada's gameplay segment. (Secret)



As your play through Leon's A Story, you'll reach a short section where you control Ada about 70% through the story. You must complete this section without using her pistol at all.

The trick to do this is to use the EMF Visualizer to solve all the puzzles necessary to proceed while also avoiding any of the enemies and not allowing them to attack you. It helps to know the solutions to this section before going in since time is quite important to your success.

Upon completing the section and going back to controlling Leon, the achievement will unlock.

Achievement is worth 20 Gamerscore.
