Portal

"Despite the rather plain environment, the graphics go a long way in creating the sterile, laboratory feel. As far as quality goes, it�s of course on par with Half-Life 2 since Portal runs on the Source Engine."

Whether or not you leap, Portal is a one-of-a-kind experience that's well worth every gamer looking into. Just take your time and enjoy, because "speedy thing goes in, speedy thing comes out" and it's over all too soon.

"Portal is a fantastic game and well worth the price of admission, particularly for those netting the title as part of The Orange Box. Valve has put together a remarkable title with intriguing and ultimately rewarding gameplay as well as some of the funniest writing in gaming today. But much like GLaDOS, Portal might strike some as huge tease -- an insanely promising play scheme cut short by criminally brief length."

"As the game reaches its apex, the scripted feel of the earlier levels is ousted in favour of something closer to a Half-Life episode. Its conclusion is funny, original and extremely memorable, as you dismantle the game's very personality and achieve a manner of revenge."

"So, players will need to learn all the tricks of their portal gun and use a combination of well-placed openings and split second timing to get through each challenge alive."
