can I play the game alone??

[KasutConverse]

was levelling up and got a 90% off coupon so I though why not and there's so much co-op around the page so I wonder if is it a necessity to have a friend to play the game??

No, there are single-player chambers, too. And, of course, the solo campaign.

[SilentHorizon]

yeah, single player chambers and single player community test chambers.

[MDZ jimmY]

the main part of the game is the solo campaign, which alone already is totally worth the price.

Nope. Almost all the 2 gig size is for the single-player. Great game, too. Probably my favorite. Not a lot of play-back enjoyment, but there's always the community workshop! ;)

I've yet to play Portal 2 but recently started Portal. I know there are 19 chambers within the game. I've viewed some of the expansion levels made by the community and they are worth looking into later on. I am curious to how many levels or chambers are in Portal 2. Can anyone be of assistance? Thank you.

Ii can't exactly tell how many but portal 2 is way beggir then portal 1. And to my opinion has a better story line too.
