You are a cast-away in Rapture, an underwater Utopia torn apart by civil war. Caught between powerful forces, and hunted down by genetically modified "splicers" and deadly security systems, you have to come to grips with a deadly, mysterious world filled with powerful technology and fascinating characters. No encounter ever plays out the same, and no two gamers will play the game the same way.
Gameplay - Biologically mod your body with plasmids: genetic augmentations that empower you with dozens of fantastic abilities. Send Electrobolts storming from your fingertips, unleash a swarm of hornets hatched from the veins of your arms, strategically turn enemies against one another with irritants.
Weapons - Upgrade your weapons at Fire-For-Effect stations located through Rapture. Craft variants of ammo and plasmids by picking up materials in the city to modify them at U-Invent kiosks.
Combat - Experiment with different battle techniques with BioShock's free form combat options: gameplay scenarios can be approached with a variety of weapons, active and passive plasmids, environmental objects utilisation, exploitation of political alliances, or a combination of techniques. Find your style but know when to adapt.
Environment - Take control of your world by hacking devices and systems: reprogram enemy security bots into personal bodyguards, modify vending machines to change prices, and transform machine gun security turrets into powerless pieces of metal. Explore an incredible and unique art deco world hidden deep under the ocean, vividly illustrated with realistic water effects and truly next generation graphics.
