No, because then it would just be called...

ORANGE BOX 2

lol

that is all

Running around as a mute with a crowbar that shoots portals while fighting zombies made by black mesa wearing hats. Fuck yea,

lol but then that would just make it orange box 2.....they win again

I think I know a way to tie them all in.

First is Team Fortress. The Reds and the Blus were fighting a world war, this war eventually was fought by elite mercenaries. Finally, one of the sides decided to make a virus to destroy the other side, this virus unleashed the infected in Left For Dead. Because of this scandal, the members of both Red and Blu, disband, and regroup as scientific companies called Aperture and Black Mesa. Eventually the infection continues spreading, so both companies abduct the smartest, fastest, strongest, and all around best humans around the world, and store them inside their facilities underground. They also put them through deadly tests to ensure only the best survive to reproduce.

Then, after hundreds, possibly thousands, of years in stasis, they finally release the survivors, who emerge among the world of Half Life. The head crabs are the remnants of the heavily mutated infection of Left 4 Dead.

The end.

Well, portal and Half life do take place in the same universe. I'm sure making the black mesa outbreak the infected in Left 4 Dead would work.

The real question is, how would valve put hats into this game?

Id get it in 3 seconds

You play the people of tf2 armed with a portal gun, in black mesa, to fight off zombies?

Left 4 Team Portal : Half Life

I actually think it would be cool if valve combined Half-Life 3 and Portal 3 since there's enough evidence in Portal 1 and 2 that they take place in the same universe, but I know it will never happen :(

My mind just erupted.

i'd call it the orange box 2

finally cleaned off all the jizz on my screen to see what im typing and agree with your statement

I would instantly love Valve if they made:

Half-Life 2 Episode 2.5
Portal 2 Part 2: The Untold Story
Team Fortress 2: Advanced Edition
L4D The Second Coming

And included them all in The Orange Box 2.

Half Left for Portal Fortress 3?

Doesn't Portal take place in the same reality as Half-Life?
