I am likely going to the midnight release. I'll be on!

Too bad it's only two player co-op. Hopefully, we'll have a party that's divisible by 2.

I'll probably get it sometime this week or next week.

Just beat co-op about an hour ago. Got all of the achievements except for four. Beating Lesson 3 of the Hard Light Bridge Course using only five portals was brutal.

How is it even possible? The minimum I counted was 6 with not a single one being able to be skipped... I mean, I kind of don't want to know because I want to do it myself. But yeah.

Ix and I just finished "world?" 3 and will be starting 4 tonight.

Also, if anyone hasn't played this game yet... don't. There's an achievement you can only get if you played with someone who's only on their first time through the intro puzzle in co-op. We could easily screw ourselves out of this one if everyone who gets this game all jump into co-op right off the bat.

"Professor Portal 75
After completing co-op, complete Calibration Course online with a friend who hasn’t played before."

After you figure out how to do it in five, I want to see it and then I will show you how I do it.

I'll be getting the game soonish, and when I do I'll post here. First person to reply gets to get that achieve.

OK I just tried two different times to get that^ achievement splitscreen. I do not believe it can be done that way. Looks like it has to be an online match. I am going to make a new profile and play it on my other 360 to get this achievement as every account in the house has already played Portal2 online.

I also just got the final single player achievement.

I am going to go back to The Orange Box and get the last three or so achievements I am missing in Portal. That way I can say I have every Portal achievement. Those OB ones are just harder than Portal: Still Alive as well as harder than Portal 2...

/blahblah

If anyone wants to hop online, we can work on the multiplayer ones tonight. Just send me an invite.

I bought Portal 2.

I have the game as well, and I am ready to play co-op. If none of you guys want to, I'll just convince one of my friends to.

Awesome guys! Now if only we knew your xbox live names... (hint-hint)

Send me an invite whenever you see me online. If I am not busy with Mortal Kombat or something, I will play for sure.

I had someone who was going to help me with the Professor Portal achievement until he played online with some random guy. So whenever anyone wants to play co-op, I'll be here.

Lantis and I both have 1000GS. Ix, if you want help with some you know what to do.
