I rented it over the weekend for the 360. It has Half Life 2 & a couple of Half Life add-ons, which were probably longer then the campaign on Call of Duty 4, Portal & some other game I never got a chance to try. Half Life 2 has to be the best FPS I've ever played. I kept doing the "one more level" thing until 5a.m. the other night.

 

Sounds like a cool game. Is it available for PS2?

 

The original Half Life is available for PS2. The Orange Box is PC, 360 or PS3.
I just returned the rental I'd go & buy it but then I'll never get my jeep back together for spring.
