After the outlandish setting, ingenious gameplay, and hilarious dialogue had all run their course, Portal left you with some pretty big unknowns. Chief among them were, "What happens now?" and "How did that whole weird situation come to pass?" Portal 2 sets out to answer these questions, and in doing so travels both forward and backward from the conclusion of Portal. The result is a sequel that doesn't try to replicate the successful formula of its predecessor. Rather, it expands upon that original experience, creating something that feels initially familiar. Yet as you progress through the enthralling single-player journey and tangle with the clever cooperative campaign, any worries that things might be too familiar are swept away by the scope of your adventure and the characters you meet along the way. Once again, you are caught up in the fantastic world of Aperture Science, where hilarious and endearing dialogue is delivered by disembodied voices and artificial intelligences, and where inventive gameplay mechanics and a smooth difficulty curve make the sublime satisfaction of puzzle solving accessible to all.
