Sword Art Online 01 - 14 [English Dub] [Thund3r3mp3ror]

Plot Summary:

The first virtual game world, and the setting of the first story arc. The world takes the form of a giant floating castle called Aincrad, with 100 floors in it. Each floor has a medieval-themed setting and a dungeon with a boss, which has to be defeated before players can advance to the next higher floor. Like most RPGs, it implements a level-based system. However, after the beta testing, the game's creator activated a system to trap the players inside the game, unable to log out; if players die in-game, or the helmets they used are removed, a strong electromagnetic pulse is emitted to kill their real bodies.
