I few days ago, I started going through all the game files and here is what I found, these may NOT be new to you, but, I find these interesting, if I make a mistake, please do correct me. (I only started playing last year, I nub).
Deployable cover, obviously turtle’s. Usable in game.
Spotting scope, ??? (If anyone knows what this is, please tell me!, im curious)
Throwing knives: Removed item, Still in augments folder. Usable in game.
Capper: New Augment?
Armour Piercing: New augment? (Does more DMG to EV, according to wiki)
