Try grabbin part12 again from another group. Like if you got it from abgx, get part12 from the terminal or from another poster.
I booted HL2 just to see how much more purdy it was as I only finished it on the first Xbox and it looks and feels excellent, great improvements, lighting is gorgeous and controls are tight.
Kinda pissed that in the IGN review they say it's a port of the Xbox HL2, which was considerably dumbed down from the PC version. Very misleading and could damage potential sales. From what I've read in the IGN and GS reviews, they are both full of lies stated as fact.. SO ANNOYING.
Just finished Portal, only 19 missions but it was awesome, hope theres more levels to come via XBL. It reminded me of Prey quite a bit, comparisons are pretty obvious.
Overall this is the best value in a single package on 360 ever, possibly on any platform ever, and I am pretty sure it won't leave my 360's tray until either Jericho, CoD4, Assasin's Creed or Mass Effect come out! Other devs need to take note, we need more great packages like this.
@hadrian I'm lookin forward to Left For Dead to man, saw a few vids on gametrailers and it looks just so awesome, kinda like 28 Days Later, the Zombies are FAST lol, gonna be so sweet online!
