Portal 2 is hailed as one of the best co-op games ever created that lets you and a friend play as two robots that have to solve various puzzles with guns that can create portals. The game was developed and published by Valve on April 19th, 2011.
Innovative and incredibly complex gameplay, an unfolding story, one of the best musical scores ever created for a video game, and more make Portal 2 an experience that you don't want to miss out on. There is a single-player campaign that is completely separate from the co-op campaign. If you play the game alone, you can expect to meet a cast of new humorous and unforgettable characters, new and challenging puzzle elements that will put your brains to the test and a varied number of new test chambers. Visit new areas of the Aperture Science Labs that have never been seen before and meet GLaDOS once again, that charming murderous computer companion that guided you through the adventures from the first Portal game.
Now, Portal 2 has a completely separate co-op campaign that has its own story, its own test chambers, and two quirky player characters. In the co-op, campaign players have to work together and think together in order to figure out how certain obstacles work and how to overcome them with the power of teamwork!
Portal 2 features a sprawling single-player campaign with a gripping narrative, a separate co-op campaign with its own story and characters, an advanced physics engine, captivating music, editing tools, and much more!
