I unlocked the Portal felt, deck, and chips in Poker Night 2 recently, which gives Poker Night 2 a little more of a science feel! As a lover of Portal, this made me pretty happy. Of course, when Brock asked GLaDOS about Cave Johnson, I got even more excited.
Here’s a video I found capturing the conversation. Poker Night 2 doesn’t have much a story, so I wouldn’t really consider this a spoiler. However, I recommend avoiding the video if you haven’t beat Portal and Portal 2. The Portal series is my favorite series, and I consider Portal to be the best game I’ve ever played. Please don’t watch it if you haven’t played those games!
