как только уитли взял контроль над всем, загадки стали душными и сложными. геймплей вкусность
I'm glad I listened to my best friend and purchased this game! We played through the entire co-cop campaign together. I was SO hooked with that experience, that I went through the single-player instantly. I then talked my partner in to purchasing it, lol.
I love Portal and the various 3rd party additions. They are good puzzle games and I love the humor in the story line.
One of the best games I've ever played

im not asking, play the ♥♥♥♥♥♥♥ game.
That was a masterpiece.
cool
This has to be one of the best games I've ever played. The enviroments are some of the best I have seen in gaming paired with it's amazing storytelling and the music, oh the music and sound effects are always on point for wherever you are in the campaign and the ending is absolute peak. if you are considering buying portal 1 and 2 BUY IT you will not regret it
One of the best games of all time
