Unfortunatley no. Unless its a Games For Windows release that requires Windows Live then it won't have cross platform play, and even then its unlikley to be included.

 

Well, enjoy some Portal-Gun action in HL2...

I got it and Portal is one of the most satisfying games I've ever played. Unfortunately I wasn't able to upgrade my video card like I wanted so I can barely run any of Orange games.

EDIT: as soon as I upgrade, I'm totally doing half-life 2 with the portal gun like in the site MnemonicSyntax mentioned.

 

I bought Half Life 2 when it first came out, and was never able to play it because of the hitches and bugs that they had with ATI cards. I was tempted to never give them my money after that debacle, but I really want to play, so as soon as my damn 360 is back from it's RRoD sojourn I'll be picking this up.

 

Aww, I didnt know you were talking about the 360 version  


Anyway, any PC gamers here wanna play some TF2?

 

I've got it too, but like a lot of other people it's behind a few other games I've been waiting to play/complete. I'll get around to it eventually.

 

I have The Orange Box on the 360, TF2 is slightly over-rated but its still fun. Saying that i've not had a standout game yet. HL2 is awesome.

 

Wow...the age of this thread really shows how behind I am with this, lol. I just got the Orange Box for my PC recently (still haven't put it on yet though). I've played Portal before, and it's one of my favorite games ever made (my brother-in-law has it). Can't wait to play the others.
