Ctrl+Spacebar = Perform a slow vault (only on hip-high obstacles with a step over animation like the one that was in the game before the proper vaulting system was implemented) balance is, that the movement is slow but your character doesn't grunt/moan.
This could come in handy when trying to sneak through a town to avoid zeds, or when sneaking up on players obviously.

Ctrl+W (while in crouch position) very slow movement, not silent of course and in proper correlation to footwear, but should allow to really get close when sneaking up on zeds/players

Ctrl+W (while in prone position) very slow movement, important to have a better chance of concealing movement when impacted by a broken leg for example

Alot has been done to make stealth more viable. I believe these additions to be quite fitting with the recent changes in regards to stealth gameplay. What do you think?

I love DayZ
