Probably fake, but....

I can’t believe it myself but if it’s true… Yesterday Valve updated their Valve Software website. New look a lot Mac-like stuff but that’s not it, they posted an image with something very weird which disappeared after few minutes.
Hopefully 4chan users managed to grab a screenshot of it and here it is:

As you can see we got a lot of stuff going on here, first of all 61810 which can be June 18th 2010 (6.18.10). Secondly, look below there’s Source Engine logo but look closer, it says Source 2, then we have EA and T2 logos.
BUT there is more, someone manipulated with the image and here’s what showed up:

That’s right, it’s the Duke. But is it true? I guess we’ll find out on June 18th.
CURRENT THEORIES:
It's Duke Nukem Forever, now appropriated by Valve.
Kleiner with an ammo belt (HL2: Episode 3).
It's a new source engine for a new Half-Life game (HL3).
It's fake.
What do you guys think?

PS Read their thread for a lot of crazy stuff, like this secret website (http://www.valvesoftware.com/hocopus/).

If it's true....
got to admit, Valve has some really sick humor. Releasing a long awated game instead releasing the expected long awaited game. Irony? Pretty much.

Meh whatever, I thought it's wotth enough to post here.

I wouldn't be suprised if it was Kleiner with an ammo belt, sounds just like valve trolling really.
Either that or it's a fake.

it is
i just don't believe it till we get something real. :)

You have to admit though, it does look quite a bit like our old friend Duke there.

"Hopefully 4chan users managed to grab a screenshot of it and here it is"
Need we say more?:P
[lazy edit:]
If anyone, ever, wanted to pick up the Pandora's Box called DNF, Valve is the last company i'd hand it to. DNF coming summer 2525 ?
[/edit]

That right there is some serious trolling going on. :P

Well, after all, Valve just announced that HL² episode 3 won't be presented at the E3, but that there will be a new game (no HL, no Portal, hopefully no L4D) announced, so who knows ?

I suspect... Left 4 Half-dead Portal-strike Fortress - Condition Opposing Shift.
You are Barney Barnacle, the half-undead tactical scoutgineer. Your mission is to save the planets poulation from comedically designed interdimensional zombies.
The gameplay will, amongst other things, consist of jumping through portals, while tossing ammo dispensers through portals at cute cyborg zombie turrets at the speed of sound, all while everyone of your allies goes around doing nothing to help your effort at all.

This a fucking joke? Cause it ain't funny, yo.

don't dis them they are quite capable at times.

DN3D On Steam. :P

For the low price of $14.99, 14.99€, or 12.49£

LOL @ "Hopefully 4chan users managed to..."
If this isn't fake... it really isn't a funny move coming from Valve, it's trolling on their games' fans.
Couldn't be Shepard, too? Shepard Adventures Ep1, 2 and 3 you know... Just like Portal.
