When it comes to making gamers feel like they're actually part of the action, no peripheral does it better than the Delta Six combat rifle.
Equipped with force feedback motors, the Delta Six actually lets you feel the recoil from every shot you fire. Unlike previous motion sensing controllers that require a separate tracking device, the Delta Six incorporates a built-in accelerometer that makes it automatically compatible with any game right out of the box. There's even variety of attachments, like a scope and a suppressor, that can be attached to the gun and provide an added degree of realism.
Although some players might not enjoy the fact that you actually have to physically remove the clip and insert a new one each time you reload, the feature really just makes war games much more visceral and teaches an important lesson.
