I for one, regrettably was slow off the mark in buying Bioshock. Even though I had a demo, which blew me away, other games kept popping up which too priority over it, such as MGS4, Resistance 2 and Killzone 2, so I only bought it last month, a long time after its release - and I had no idea what I was missing!!
Bioshock is an incredible game - its something you experience as well as play. Very few games in the last few years have even come close to this deep, immersive, atmospheric game. Even though at the grass roots, it is fundamentally an FPS, it strives and succeeds to achieve a lot more. The setting itself, the underwater art-deco utopia of Rapture is like nothing I've seen before, yet captures every element of every fantasy film, whilst retaining a very real, and gritty base. The characters themselves (mainly splicers) are themselves victims or casualties of the DNA splicing that makes this world what it has become. But I can't emphasise it enough that the atmosphere is just breathtaking, graphically it is beautiful yet deep and solid, you really feel like you're, but not just because of the graphics, the sound and music is also oustanding a really adds to the tension and feel, all this and I haven;'t even mentioned the gameplay!
The feel and control of the game is solid, the weapons handle with enough bang and fizz, especially when upgraded, the characters move and react so very reaslistically, you also have additional DNA enhanced powers called plamids, which are mainly used offensively to compliment your arsenal and open up genuine creativity and ingenuity as to how you assault each enemy. You are further drawn in by the addictive nature of enhancing your abilities, both physical, engineering and skills - whcih as the game gently but assertively progresses, you will need all the help you can get.
Which bring us to the final point I wanted to cover, the little sisters and their huge, mute, protectors - the big Daddies. Its this partnership itself, that makes this game utterly unique and completely spellbinding - NEVER has a FPS achieved such an emotional pull from its gamer. Their co-dependancy is fascinating, and you will never have seen anything a game before that really invites you to ask questions about your self and the decisions you make - it almost literally makes you accountable - as the little sisters carry the basic element - Adam - which can fuel your powers and make you stronger....but you risk a lot in trying to get to her and then you risk her life if you decide to take it - it really does yank at your heart-strings.
I could literally take days to explain and cover everything that I love and is great about this game. But it is an absolute one-off. I only regret not buying it sooner, it is the most, well concieved, beautifully realised and utterly immersive experience I have ever enjoyed on a console. An absolute masterpiece.
