It is much more challenging than it looks.Д¬hamber 15: I lost a few seconds on this level, but it wasn't too bad.Д¬hamber 16: I got the portal bump pretty quickly and then just used the cube to make it through the rest of the chamber.Д¬hamber 17: This level involves another use of the portal bump. It could probably go a few seconds faster though.Д¬hamber 14: I barely got the skip on this level. PC cannot do the final portal placement allowing me to not have to use the cube.Д¬hamber 13: There isn't really anything special in this level. I would hit my head many times and have to restart here.Д¬hamber 12: This is one of the few test chambers in which console has an advantage to PC. If you get it placed just right, you can jump through on one side of the door and then jump out on the other.Д¬hamber 10: In this chamber, I peek-a-portal to skip one of the jumps and then I use momentum to go straight to the chamber lock.Д¬hamber 11: The jump to the portal device is a little more inconsistent than it looks. Sometimes when the door closes, it will make the portal disappear. The trick is to make sure that you hold forward the whole time and time your jumps correctly.Д¬hamber 09: This is another chamber that is a little random. You have to get the portal placed all the way in the corner and then jump onto the protrusion to curve around to the platform.

I had no such luck, so I lost about 3 seconds or so.Д¬hamber 05: In this chamber, the elevator does not move until GLaDOS finishes her speech.Д¬hamber 06: To skip this chamber, you just have to shoot one on the ceiling and then jump through to land at the elevator.Д¬hamber 07: You are also able to skip this chamber by placing one on the wall and holding right as you go through it.Д¬hamber 08: This chamber took me a little while to perfect. If you get the portal just right, SOMETIMES, it will land the cube will land directly on the button. You must wait one minute until the portal opens, and then run to the chamber lock.Д¬hamber 01: This is another level that you can't really save time on.Д¬hamber 02: You must wait for GLaDOS to speak until you can go through, so this level can't really be improved either.Д¬hamber 03: This is the first level that really matters, but there isn't much to it though.Д¬hamber 04: This level was a serious pain. Glitches used: Portal Bumping, Peek-a-Portal, an edge bump in Chamber 18, and using the turret to knock off all of GLaDOS's cores.Д¬hamber 00: There isn't much that can be done here. General Notes: Accelerated Backwards Hoping (ABH) cannot be done on console as well as some portal bumps. I timed it to be 20:31, which is about 29 seconds faster than Cody's run. This is a single segment, non-OoB run of Portal for the Xbox 360.
