The Adventures of 00 Dilly

This is for hitting the bullseye on every billboard, including the bonus levels. You’ll know you did it right when the billboard flips around and shows an advertisement. Heads up that my achievement popped on the last bonus level just when I saw the billboard from behind using the rocket, so you could perhaps use the rocket to ‘see’ the billboard and pop the achievement though I wouldn’t risk it other than testing it out on the last bonus level.
