Portal is a brilliant, fascinating and often hilarious adventure. It introduced players to a hitherto unseen gameplay mechanic and took it to extraordinary levels, creating a fantastic experience. However, there were a lot of questions players were left with after the game ended. If you played Portal, you might’ve found yourself asking “OK, I’ve beaten this evil computer. What do I do now?” or “How did I get here in the first place?” Portal 2 attempts to answer some of these questions by travelling both into the past and the future from where the first game ended.
