The sequel takes place hundreds of years after the original, but players will still control the same character, Chell, who was apparently in stasis for that timeframe. Awakened by one of GLaDOS' personality cores, Chell inadvertently wakes GLaDOS and thus begins the twisted journey of dodging personified turrets and escaping deathtraps. Besides polished graphics and co-op, Portal 2 features new gameplay elements including tractor beams, paint-like gels and more.
