most fun Ive had in a portal game it may not have coop but you can still download custom maps and put them in to the game files you can also do backhopping which you cant do in portal 2 you can also do the challenge modes which make the game harder but thats also in portal 2 but its different slightly here so id recommend it 10/10.
Great game, a real puzzle game. Wish VALVe could count to three though. This game is one amazing brain teaser wrapped up in a little amazing bow.
Once upon a time in half-life universe, there was a hidden research facility.
Portal is a great puzzle game. Some levels are easy, some are harder. Glados is a great companion during the game. (spoiler alert) Although she tried to kill you, we all love her. GLaDOS is a legend now.
Nice Game!
its a really good game the puzzles are tuff but not too tuff and the action is awesome you will love this game
Great puzzle game that requires you to think with portals
One of the best puzzle games out there.
the moment where GLadOS said "ITS CAKIN' TIME" and cakes all over the place was the best moment, but not better than the protagonist saying "ITS PORTALIN'TIME" and portaled all over the facility
