And because things being diegetic in the universe is always a big concern for our game, what about [FPS scanning] when you're not wearing a helmet?

So there will be lenses, but the idea there is that they're quite high tech and expensive. So you won't necessarily be going out and buying them from your local supermarket; that's going to be high-end tech that you have to pay quite a bit for. So the helmet is going to be the primary method for quite some time. There are some things that utilize the signature system. So for example, we've got the mining tool that's using signatures to find resources and whatnot. So there are other devices that use the underlying system, but in terms of the core gameplay, it's going to be helmet-based.
