[coolboyali2007]

awesome trailer ever-made Valve are truly genius!! AMAZING!!!

[wallefan10]

my school went to see a play and one of the actresses was Ellen McClain (voice of GlaDOS) i luv this game

[Elrhino123]

I think the Beta portals looks much better than the ones they have in-game now, I liked the particle effects around the portals more =3

[bigbaldin]

the cake is a lie

[digitaltrekkie]

Remember: If at first you don't succeed, you fail.

[Link1021l]

now your thinking with portals.

[Falador321]

This is a REALLY old version of the game...

[ravemario]

a beta virsion

[JamiePS3Howitt]

just got this in the Orange Box.

AMAZING!

[MadnessFanMS]

wait a sec. what happens if something is blocking the portal?

[ryandoesnotsmell]

well i guess you probably wouldn't be able to get through. When i played it i found that the portals work like doors. If that was blocked, yuo just wouldnt be able to get through, right?

[thiefmasta24]

well first of all the condom goes on the dick so yea answer ur question i hope

[wrathman13]

please come out for xbox360

[Nectrocisys]

Have you ever heard of The Orange Box?

[wrathman13]

I looked it up. Seems pretty cool.

[AlterEG6]

it already is out..BUY "The Orange Box"!!! Included: Half Life 2;Episode 1 & 2, Team Fortress 2, and Portals.

[wrathman13]

I really will get it. Looks like a masterclass of a collection. I would really like to play that remake of the first half-life.

[dz4ztr]

If at first. You don't. Succeed. You fail.

[tsukinoneko]

[jimmybob127]

[HXXXXAN]

Coool as hell!

[kneegrownugget]

lol looks hard

[frosticex]

SWEEEET!!!

[Valias]

This looks awesome!

[anata22]

is this some Pray portal ripoff?

well yes sir i think it is.

[matthewwegner]

No, Portal is being created by the team behind Narbacular Drop, a project by Digipen students and released in 2005. It predates the public release of Prey (and the concept of portals has been around far longer).

[virginpusher]

thats just plain ol friggin sweet

[mmnin]

surprising they haven't thought of this before, but i'm glad some developers are thinking out of the box.

[Foodisgood]

awesome

[Heartshapedbox1]

:O looks mad

[princessmulan06]

Not gonna lie...that looks really cool.

[superlolz]

Teh pwn. Eps is a must buy. :P

And TF2 gameplay footage hasn't even come out yet...

[pipe76]

tf2 is the dream imho, who can realize the potential of first Team Fortress - any tries ends. Popular games have suxxor quality of process, couse they dont have the team which works on Quake 1 and Team Fortress mod. Sry if you mean another game or else,gl, good hunting

[matthewwegner]

BTW, for anyone finding this video directly through YouTube I run a site focused on physics-based games (where I talked about Portal and linked to this video): http://www.fun-motion.com/

[hancmd16]

This is THE evolution of gaming

[JackofAllHades]

TF2 looks better.

(haven't actually watched this yet)
