From the preview by PC Gamer's Quintin Smith:
"Developers are getting so good at pushing our buttons with their RSI-afflicted fingers that it's becoming genuinely scary.
Consider the R6V:2 experience point system, expanded from the original R6 Vegas. During our recent multiplayer playtest I caught another player running into a wooden cupboard to prepare an ambush. Making use of the new bullet penetration I peppered it with rounds until a sharp groan told me he was dead."
