I really enjoyed the first Portal video game, it was a much needed break from the first person shooters I had been playing that were focused on violence.
Portal did not disappoint, the levels grew progressively harder as the game went on and the payoff at the end was spectacular. The GLaDOS song at the end of the game is fantastic.
Now we have Portal 2, I played it using Steam from Valve on a MacBook Pro. There were no slowdowns, frame-drops, or stutters during the game, and the audio was great.
It took me about 50 hours to play through the game, there were only a couple of levels where I got stuck and spent more than 20 minutes trying to get past. There were also plenty of levels where I died a number of time, but death in Portal is no big deal, you start over in the same puzzle close to the place where you dies, you even get to keep a lot of your progress in many of them.
Another great feature of Portal 2 is that it is easy to create your own puzzles and share them with the world. There are tons of player created levels available to play and they are a great way to add re-playability to the game.
From the Portal 2 web site:
The sequel to 2007’s Game of the Year, Portal 2 is a hilariously mind-bending adventure that challenges you to use wits over weaponry in a funhouse of diabolical science.
Using a highly experimental portal device, you’ll once again face off against a lethally inventive, power-mad A.I. named GLaDOS. And this time you won’t be alone. Meet an expanded cast of characters as you think your way through dangerous, never-before-seen areas of Aperture Laboratories.
Break the laws of spatial physics in ways you never thought possible, with a wider variety of portal puzzles and an expansive story that spans a single player and co-operative game mode.
I rate this game a 9 out of 10 and recommend it to anyone who loves first person shooters and puzzle games.
