I'm creating a whole thread for this game, because I just completed all six advanced levels and I want to shout that from the rooftops.

Satisfying indeed. Now if only the dlc for Portal 2 would come out already ffs.

yeah wasn't that supposed to be this month? I bought Portal 2 like 3 hours after finishing Portal. Clash, if you haven't played Portal 2 yet, definitely give it a go. An absolute gem. I haven't tried the co-op mode yet (just finished the single player), but I've heard great things about that too.

I will definitely get Portal 2. The first Portal is one of the most enjoyable and satisfying video games I have ever played.

Yep, soon after it came out they said the dlc would be out in the summer. Then that turned into mid-September and now here we are...

But yes, playing the co-op is an absolute must. I played it split-screen with a friend of mine and it was easily one of the best vid-game experiences I've had. I'd imagine playing online co-op would be too frustrating, but not impossible.

There are actually quite a lot of really stellar custom maps that you can dl for portal and portal 2.
