Author: Irrational Games

This spiritual predecessor to the Bioshock series still manages to captivate gamers with its significant improvements over the first title. It introduces several classic RPG elements with weapon upgrades, stats, and a generally improved combat system.What makes this game so great, however, is the repetition of its selling formula. Set in a semi-cyberpunk world, it tells the story of a soldier, woken early from his cryo-tube. An illegal implant in his head and a bout of amnesia point to something very awry, and you'll be making your way cautiously through the game's chilling environment as you try to discover what happened on the spaceship.It makes for a tense exploration experience, joined by fantastic AI and voice acting, a variety of enemies, and the ability to play the game how you want. You can focus on combat, psychic powers, technology, or stealth. You'll find your heart pounding in your chest as you navigate one of the best survival horror games around.
