Yes, my English is very bad
To increase the immersion in the game, and take a more practical sense to use one or another helmet, that is not simply that it protects, my proposal is that those helmets somehow limited vision, has its visual replica in the game .
Thus, not only will value the helmets, for a numerical data, but also for its practical implication of using them.
The easiest way to do this is by including a layer or layers, between the world and our interfacing.
Different models for different hats.
In addition, you can make this layer, react to our movements, as well as beatings, like many shooters today have optical view of the weapons that react to player movement.
In this video for example, which is a mod for ArmA2, we see optical sight reacts to our movement, with an effect of skidding, i like the 2:30 minute also reacts to recoil, it would be like if will impact us with a melee weapon.
Also, imagine this, with Oculus Rift really have the feeling that wearing a helmet on his head, what else would help the device itself, to have something really in the head.
Itās easy to implement I think, and it takes us a little more into the game.
