Thanks to this thread I finished Co-Op last night with a fellow GB User, and all without voice chat too, was great!

Kandycane2029 on 360, Mountain Time. I usually play evenings, but I'm off work all this week, so I'll be on at just about anytime.

I'm on PC, usually on at nights and weekends PST

I already have finished the first two chambers with a friend of mine, but he left me to dry while he ran off with some other robot that night.

I play mostly evenings 9pm to midnight central time.

Goddamn PSN outage.

You guys, go have some fun.

I can play some Co-op. I've finished it, but I can play it. Add me if you want.

Well, I've only got a playstation 3, but the network will be up soon (hopefully). Finished it all, but still fun.

JUST finished the game today so would like to start on the co op when I can.

Steam: EoinJ

Based in the UK

Haven't done the co-op yet.  Been hoping anyone I know locally would have bought and played it, but no dice.  So... Anyone that hasn't played it yet, feel free to give me a shout.  Night's are usually the best time during the week for me, but I'm available all day on Tuesdays.  Sunday afternoon, as well.

Steam ID: Progman 9000

Just beat single player but have no friends who have the game to play co op.  my xbla gamertag is Punisher Kaos 

360 gamertag is apathy valley. I'm on now and I haven't played before so would need to start from the beginning.

Anyone who wants to do 360 co-op, my gamertag is Stern Cat.

Anyone want to play co-op on 360 today or after TNT? I'm back home for the day so I might as well try it out while I have access to my Xbox. My GT is talarata.

I'm playing on Steam. I'll gladly play Co-op. I need the Professor Portal achievement, so if you haven't played co-op yet, please, please, add me as your friend and we'll play it together. At least the first time. Please.

Okay, so I just finished co-op and I have a dilemma - I only need 2 achievements to have them all...

I'm sure this is just a stab in the dark, but I need to find someone who's never played Co-op at all so I can get the 'Professor Portal' achievement (in fact, this could contribute toward the Friends List with Benefits achievement, as well).

In return, I can go through all of Co-op with you and help you get all of the co-op achievements if you are so inclined (I am a very good Portal buddy :)).

Gtag: MEETSP1NNER

Here's crossin' my fingers that someone can help a brother out.

Hey everyone, is anyone still looking to play some Co-op on Xbox 360? I just finished the single player now and I'm itching to play some more. I am going to be free all night tonight so if anyone is down, either reply to me here, send me a PM, or message me on Xbox Live at Kurtdyoung.

I just beat the single player and would like to play some Co-Op. If anyone is interested please add me. My gamer tag is Barrock.

Consider all your asses added on Steam and on PSN!!!

Ready for some co-op after completing the campaign.
