I have no clue how I missed this before. For that I apologize. But this just popped up and I thought I'd pass it along. Not to mention file under Fucking Awesome.
What is this? It is a vest that replicates force effects from games and translates it into something you actually feel while playing your favorite game. What kind of things? Well, environmental effects, punches, jabs, gun shots and other in-game dynamics. What makes me really sad is that this year at E4All they are showing off the vest for the newest game they have added to the list of supported games.* What game you ask? Well World of Warcraft. That's right, you will be able to feel that chest crunching hit from a Death Knight or when you are on fire from an Undead Mage setting you on fire. Pretty friggin sweet. All for the price of $169.99. Check it out while there if you are making it, Booth #428.
Oh, the other games it works for, Rainbow Six Vegas 2, Mass Effect, Bioshock, Call of Duty 4, Crysis, and Quake 4. To name a few. Here's their site if you are interested in more. http://www.tngames.com/
* I just found out I can't make it to this year's E4All, just as a side note.
