This is a video showing how to get outside of the BioShock demo for the Xbox 360. The method for getting out of the level was discovered by YouTube user DeathGlobe, and it was filmed by yours truly.
This glitch involves pressure launching between plants and a baby carriage. Yes, a baby carriage. After you get out of the elevator, you can get the baby carriage you'll need by going to the right and killing the splicer that's holding it. Now, push the baby carriage to the far left of the banister near the memorial for that random guy.
Now that you've got the carriage over, you're going to need to position the carriage. Check out how I set it up in the video to see exactly how I did it, because I can't explain it very well. To get launched you're going to want to run at the gap between the two objects and jump when you're stuck in between.
This glitch is not easy. I mean it! The video you see here was the result of MANY attempts, so don't feel disheartened if you can't get it on your first try. It will probably take some experimentation to get it down right.
I hope you enjoy the video...
P.S. If you want to check out Part 2 (getting down to the bottom and to the guy knocking on the door) you can
