If you purchased the BioShock 2 Collectors Edition you could be forgiven for passing over the 3 posters that were included as just being standard, almost boring posters. I know that’s what I thought of them until earlier today when I read about the hidden messages.
Hold the posters up to a blacklight and what do you know, there are hidden messages within each poster. What do you mean you don’t own a blacklight?!?
In that case you’ll just have to be satisfied with looking at these images.
