No, they actually supposedly work. I assume its going to be just like the cheap kiddy toy ones, aka the "eyeclops night vision" Basically it just uses a screen, a camera, and IR leds. But I'm getting it and no matter the price!
By the way, its 150$, which I'd say is a pretty good price, the eyeclops night vision things average around 80$, and I wanted to play with those, but now I'll have this!
I'm not willing to buy an FPS on my PS3, but if this is available for PC I might go for it. I absolutely loved the first one and still play it fairly regularly.
