Are you a video game buff hungry for an addiction that will last for hours? Or are you the kind who loves a beautifully structured plot?

Either way, “Portal 2” is the way to go.

Developed and published by Valve Corp., “Portal 2” is a first-person puzzle video game released April 2011 for Microsoft Windows, PlayStation 3 and Xbox 360. While retail versions are distributed by the developer Electronic Arts, Valve’s delivery service Steam provides for Microsoft Windows on PCs and Mac computers.

As a sequel to the original 2007 game “Portal,” the plot reintroduces the player to a young woman named Chell.

She has awakened from stasis and is required to navigate through the Aperture Science Enrichment Center with a portal gun, which shoots portals on white surfaces allowing Chell to travel to different places. GlaDOS, an intelligent computer, is rebuilding the facility in the meantime.

A British-accented computer named Wheatley and a man named Cave Johnson are introduced in “Portal 2.”

Special features in the game include single and cooperative multiplayer modes, story mode, and the ability to create your own or explore other players’ test chambers. Additional gameplay elements such as light bridges, lasers and gels are also included.

“Portal 2” has been well-received and universally acclaimed. It ranked second in Time magazine’s Top 10 Video Games of 2011 and received a 95 out of 100 in the review aggregator Metacritic. It is one of my favorite games.

“Portal 2” can be bought in stores or online. If you haven’t gotten your hands on a copy yet, be prepared for an adventure into a new world, and hang tight because it’s going to be a blast.
