I thought about an idea of Grabbing enemies, the only game that implemented this mechanic was The last of us games and it is one of the best mechanics (in my opinion) ever and also to make it more realistic you can shoot the hostile you are holding in the head but also the enemy you have hostage could find an occasion to slip out of the grab making it more realistic. another cool feature in The last of us was that you still could grab an enemy without having any ammo and when you pulled the trigger and they heard or saw that you have no ammo, they would get out of the hold. i hope this will be implemented in the game. i think this is going to best stealth game in YEARS.
