Bioshock Infinite originally released back on the PC, PS3, and Xbox One as the third entry in the series. The video game acted as a prequel to the franchise and focused on protagonist Booker DeWitt on his mission to escort a mysterious woman Elizabeth to New York. Needless to say, their journey is a perilous one filled with political uprising, time traveling, multiple realities, and a giant metal bird. Bioshock Infinite was generally met with positive reviews for its fun gameplay and compelling story line, but looking back at its previous trailers, we can see that the game went through some extreme adjustments.
The E3 2011 demo and another 10-minute gameplay demo showed off some scenes that never made it to the full game, like more active Sky-Hook battles and hostile NPCs. Similarly, while the final game kept its core features like the floating city of Columbia and the Vox Populi, the demos seem to expand on what they were meant to be. Columbia was literally flying through the sky and across the world while the rebel group was ruthless and hostile when it came to fulfilling their goal.
Elizabeth had also gone through plenty of changes during development as she was originally meant to be a mute woman. Even when they decided on her role, she still went through plenty of cosmetic changes, especially her facial features. Her original abilities, on the other hand, revolved around psychic powers like telekinesis and heat combustion instead of opening Tears.
Judging by the previous trailers, it seems like Irrational Games had to scale back most of their ideas during development. Nonetheless, the retail version of Bioshock Infinite is still a great game all on its own.
