I've messed around with this cheat quite a bit and had some fun with it exploring glitches and such. Thought I would share a bit. First off, though, you may ask "which cheat again?". It's a cheat that allows your portal gun to shoot a portal almost anywhere. The only exceptions are places that aren't physically a wall(objects, blocks that are a part of a wall, but not considered thus, etc...). To activate it, you pres YABABYYA, left, right while playing the game. You'll see some text on the left of the screen to confirm it. You should be able to do the following, too;

1.) Portals in the elevator/elevator room:
If you shoot a portal at the walls surrounding the elevator, you can successfully create a portal using the cheat. You can also make one in the elevator if you shoot the door as soon as it closes on you. May take a couple tries to pull it off.

1a.) Fun with this glitch:
You can only do anything special with this during he time between when you receive the single portal gun and when you receive the double portal gun. The orange portals spawned by the game will NOT dissolve when you go through the field, so you can connect portals to the elevator room. This can allow you to bring objects that would otherwise be destroyed into the elevator(have not tested this) and even allow you to 'escape' the elevator.

1b.) Escaping the elevator:
This may take a couple tries. I found this worked best on the first momentum test. Try to quickly shoot a portal at the elevator. You'll notice you can't go through it at all and it will stay behind as the elevator moves up. However, if you try jumping into the portal before the elevator moves, you can get out. This will result in you being stuck in an area above the room, while the elevator leaves upwards. Escaping the area is possible, though I forget how I did it. Just try to explore it until you find your way out. Not much new. You'll realize the areas under and above where the elevator was are blocked off with gray circles.

2.) Portal on portal:
WIth this cheat you can shoot a portal of one color on a portal of another color. There are no real glitches I've discovered with this, besides some lag you may get with the portals, but it does have one cool use. Shoot two portals in the same place on a wall and you will get a mirror. That's right, you will be able to see how ugly your character actually is. Going through the portal will yield the same affects as normal and you will come out of it. ON the wall, it's the same as going backwards. On the floor, it's just going to send you upwards over and over again until you leave.

3.) Acid trip:
You can also use the cheat to shoot a portal into the acid floor. Again, no real use, but it can be fun. You can have fun with it by shooting a portal in the wall and one in the acid. You can walk into the acid and return unharmed, kind of like escaping being shot by a turret, damage-wise. Jumping into the acid portal, however, does not work. If you try it, you will float slowly in the acid and end up dying on top of the portal.

4.) Jumping off the world:
Sometimes the game will not like your choice of portal placement and going through it will cause you to fall off the world infinitely. The one place I've been able to get this work repeatedly at is during the escape, the room with the gate you can shoot through blocking the way to an area with the low ceiling you're supposed to go into with a portal and duck through it. If you instead shoot a portal into the pipes in front of you and go through another one, you will fall off. This has happened to me in some other areas, but I haven't been able to replicate it anywhere else. To escape, just load the previous auto-save.

5.) Pretty colors...:
You can use this glitch to also get to areas you aren't supposed to access. A couple examples are areas behind some of the gates you can shoot through and, most notably, the other side of the room you try to access, but fail to do so when the ground opens and turrets pop out of the walls. Going to these 'forbidden' areas will result in the rest of the world looking funky and changing colors. You can escape these areas by going back the way you came from.

6.) Hanging on tightly:
Shooting a portal behind objects attached to the wall that aren't supposed to fall off will keep the objects in place and allow you to see behind them. These include cameras on anti-portal walls and the energy ball dispensers/receivers.

7.)Purely aesthetics:
There are some portals you can shoot with this cheat but you won't be able to go through them. You can use this to look through the portals, but you can't enter them. They will act like a wall or floor. Places you can see through are also 'forbidden' areas, the difference being that they're the areas that you couldn't explore anyways whether due to small pillars blocking you or a drop that the game doesn't plan for you to fall down. For example, the turret assembly line. This also happens if part of the entrance or exit portal is on a part of a wall it can't be on.

Those are some cool suggestions. I really want to mess around with the Portal gun in the Half Life games though, I know there's a mod available for the PC version that allows you to do that. I can just think of some of the cool things you could do, ambushing Combine and actually getting closer to the G-Man on certain levels.

Yes, I really want to use Gary's Mod, too, but the game is for PC, not Mac, so I'm stuck with the 360 version. On another note, I found another glitch just now that I don't know how I activated it:

8.) Glitch room:
Somehow through messing around with portals in the 'impossible' test chamber, when the elevator moved to the next floor, I entered a glitch chamber. Can't move in it at all. And it has a white ring on the otherwise gray walls and a blue beam in the middle. Trying to get a pic now.

Here's a bad quick picture:


I discovered that what happened was that somehow I started the level head above the elevator top. I discovered this after killing myself using the energy ball cheat. I don't if/how the portals came into play, though

And also, the falling off the edge, I retried it and remembered that you have to go back through it to fall. So, shoot the pipes with one, wall with the other, go through it and then go through the pipes again to fall off.

Sorry to double post, but I find a cool new thing.

9.) Balls:
With this glitch, you can make random floating balls of portal energy. Go to the pathway to the computer battle, the walkway surrounded by glass. Shoot a double portal at the glass and go through it and come to a stop. Then shoot a portal of either color at the door and an energy ball the color of the portal you tried to shoot appears in front of you. They don't disappear and, if you make enough, it gets laggy when you look at them. If you shoot a portal at the door and then away, you'll have to enter the portal again to make more. If you stay in place, though, you can keep shooting portal balls at the door.

Edit: This appears to work with any openable door.

maybe it possible TO SAVE COMPANION CUBE!

You could place a portal at the bottom of the incinerator and save it perhaps.

And I was under the impression that cheats were PC-exclusive. Is this correct or can I activate cheats on my 360?

I gave the code for the 360 on the top of the page. YABABYYA if you missed it.

You can do that I think, on earlier levels only, though, when you have only the blue portal. The orange one doesn't disappear when you go through the force field thing. On later levels, though, like the companion cube one, you control both portals so they both disappear through the force field. You would need to affect the force field to either let you bring objects through, not close the portals when you enter, or allow you to shoot portals through it.

Man.. why the *bleep* did I think this was the portal staff forum and I was gonna ask why is he posting portal exploits when all the admins were here to see it! >___>

quote Donnelly

Well, I'm trying to save the companion cube just now.

I put a spawned cube (Down, B, A, B, Y, Down, B, A, B, Y) and put the spawned cube into the incinerator.

If we can find a way of getting items into the elavator we could be onto something.

place portal b under companion cube change the portal gun i.d and go through emancipation grill then change back to old portal i.d and shoot portal o at wall in elevator area and boom companion cube can follow.

if you shoot a portal then change the gun i.d the portal shot before you changed the i.d will not dissapear but cannot be changed until you go back to the old portal i.d

There not exploits,at least not in my opinion since you need cheats to do this stuff while explpoits r things that make the game easier w/out cheating.And even then they r not exploits in valve games since they encourage you to think of weird stuff thus making them ninja not exploits.

Stormthehouse, triple post fail.....

Is there any other cheat and can I have the code?

I mean for Portal not Half Life...
