What G-Man keeps in his briefcase...

Episode One

"Did you discover the prototype Hunter?"
The Hunter, Episode Two's relentless new enemy, was already in Valve's collective minds by the time Episode One was being developed. And here's the proof - a prototype of the mini Strider. You can't see it on 360 or PS3, as there's no 'console', but on PC just type in the following commands:

"npc_create npc_ministrider"

Episode Two

"I see the Valve designers really like Lost"
Episode Two's action is interspersed with two references to hit TV show Lost. First, there's a blocked off room early in the game's mine location, which holds a computer that should be familiar to any Lost fans, complete with blinking line of numbers. Second, eagle eyed gamers have spotted a clear use of the Dharma Initiative's logo printed on a wall.


"Did you see all the info on the Aperture Science website?"
Part way through Portal you discover a grimy room outside of your lab environment, with writing scrawled all over. One missive reads "cjohnson" and "tier3". Use this info to login to the webpage, and type 'notes' to read a history of Aperture Science's technologies and research.

Or, use the login 'Admin' and the password 'Portal', then type 'Thecakeisalie' for an amusing/chilling message from an Aperture Science staffer. You can check our Portal guide for more commands.

"The cake isn't a lie - and I have the recipe"
Later in the game you'll come close to the same monitors that can be spotted through the warped glass of the test environments. And, spooling endlessly across them, is the garbled recipe for the mythical Portal cake. Yum.

"Aperture Science are keen on beating Black Mesa"
During Portal's endgame, you'll have two chances to catch Aperture Science's take on Black Mesa and how it plans to compete in the lucrative Department of Defense contract market.

    The cheats were not a "reference" to Quake. Half-Life 2 runs on the Source engine, which is a heavily modified version of the Goldsource engine, which was a heavily modified version of the Quake engine. There is therefore some Quake code left over in Half-Life 2. It's like a tower of duct tape.

    Is it sad that I actually knew some of these? No? Good. I'm a Half-Life geek and proud of it. A Halfian, if you will. Thanks Games Radar for your articles on Valve's best series. But why does everyone give the Orange Box a 9.5 or lower?

    Oh you missed one, During the portal end fight, the blue orb is saying what i believe is the cake recipe. I heard something like 2 tsp of chocolate

    You messed up on the part about Dr. Kleiner, he's on the cover of the fictional magazine, Popular Scientist.

    i found somthing that wasnt mentioned. if you the noclip cheat and go into the projector room, there are a couple of clipboards, a few of them discussing Gordon's HEV suit. Unfortunatly, the only words that were readable were the words "Hazardous Enviroment Suit" and nothing else but this certanly proves that Aperture will be the new Black Mesa seeing how it got blown up in Opposing force if i remember correctly

    I went to the Apeture website and after going through the login found a Christmas vault with the cake and Companion Cube and still alive hymn music kinda creeped me out

    Another random thing about Portal: after you escape, on the wall of one of the side rooms, you can see a picture of a "little, good jellyfish", and more famously, in a different room is the "big, bad jellyfish".
