Doesn't it bug you in games when non-supernatural heroes or villains can fall from hundreds of feet and survive without rhyme or reason? Or for that matter, falling 20 feet almost kills them out right. It is a mix between realism and game play that designers have to take into account. Do you forgo realism in a major way for game play sake or do you try to fake it? Mix in the ability to portal hundreds of feet into the air, sometimes on accident, and now you have a real issue. But it looks like minds behind Portal 2 have the solution.

As part of their continued media frenzy leading up to next week's launch, Valve has brought another trailer show casing the special armor and leggings that fix the worry of realism/game play. While it really doesn't serve up more than a basic explanation for sticklers, it is at least fun. Least to mention some more footage of actual game play. Also, they kind of make sense for the kind of real world mirrored in Portal.

No these should be made and part of some "Epic Fan" edition. Make it easier for all those Cos-Players out there who are most likely going to try and mimic these. A world of advice, look into some of the technology for prosthetic legs. The armor looks to have a modified version of the spring used for the running prosthetics. At least they do to me.
