Bioshock is a great series. All 3 games in it at a base, are quality games. The first 2 games are great games in most or every aspect. Bioshock Infinite on the other hand, is not great in most aspects. At the base of it, it's a average game. It has a good story, enjoyable characters and great art direction. That's as good as it gets with Bioshock Infinite. The actual game itself is a Call of Duty game with less variety and more repetitive level design. They took Bioshock, a first person shooter game with depth and variety and turned it into Call of Duty: Bioshock. I think the game suffered from this. Instead of being able to freely explore the levels and then continue the story, the game forces you to go in one linear direction fast, rushing you through every level into an uninspired shooting gallery every time. Every single mission is you running through somewhere while killing officers throughout with shooting gallery's at the end. The final mission is just one giant shooting gallery really showing how uncreative and uninspired the rest of the game is.
It's so repetitive and shallow. The powers themselves feel like they're only there so this game could be called Bioshock. They don't have any real function in the story and don't really change up the gameplay. I also need to mention the huge lack of weapon variety. There's only about 4 or 5 weapons you use in the entire game and they all feel the same.
Bioshock Infinite is way too linear barely offering the players any variety throughout the game. It's a strictly linear game and this does not fit the Bioshock series well. The first 2 games also had linearity but were way less linear. The plasmids are only there so it can be called Bioshock, the weapon variety is lacking and all around the game feels like a repetitive, boring shooter with a story.
Stuff like an emphasis on choice, being able to make decisions that have impact on both the story and gameplay, open level design, a constant struggle to scrounge up supplies, blending of gameplay elements and story telling and to a lesser extend stuff like research, hacking, satisfying weapon upgrades, etc are all gone in this game. This is why it's the worst Bioshock game in my opinion and I hope Bioshock 4 doesn't take inspiration from it.
