Someone told me it did as a tip to conserve air supply, just need to know if it is true. If it is then that's very realistic.
Hmm, I thought it increased your breathing rate, and made your filter fog up less, but I'm not sure if it affected time (I was always confused about how the filter counter worked).
If it did or didn't this has to be put into the game. It shouldn't be that hard. I do some programming and all you have to do is make an if statement that says if you're sprinting then the air time goes down by say an extra 10%.
No it's not really hard...they can just set it to where the time goes down about 5% or somewhere around that. Not really that hard. It's just a matter of guess and check...
