When you are near doors and you use secondary grenade function (there should be icon that alert you):
1. step - you open the door for a little, covered by wall
2. step - you ready grenade
3. step - you throw it behind door
4. step - you close the door
5. step - boom
Also there should be another door feature to open them a little, just enogh to check situation behind them by one eye. It should be done by open key when you hold it. The duration of observing will be long as you hold open key.
There will be also penetration system for RO 2 so you are dumb enemy is able to shot you to head behind doors. But if enemy dont spot you ... :IS2:
