Novint Technologies just announce a huge agreement with Valve to add support for the evolutionary Novint Falcon 3D controller (read more about this amazing technology here: http://home.novint.com/products/novint_falcon.php) to some of Valve's most popular games including The Orange Box, Counter-Strike: Source and the Half-Life 2 series.
When used for FPS (First Person Shooter) games, the Falcon allows gamers to experience a more realistic interaction through advanced force feedback (feeling weapon recoil for example) while maintaining highly accurate controls. For an even further realistic experience, a Novint Falcon Pistol Grip accessory is also available.
For those of you who want to take your gaming to the next level, this may be the next game accessory investment for you. However, at a price tag of $189.99 US, it's certainly a hefty one. Start saving up now...I know I am.
