Empty Hands
I recently found out that you cannot deploy with a slot in your inventory being empty (Dunno if it’s the case with other modes other than Spec-Ops) – Apparently it’s intentional, according to other people.
Sure, you can just fill the other slots up with guns/items and not use them, but I do miss when "equipping nothing but a knife" was an option.
Introducing: Empty Hands!
It’s literally a weapon that does NOTHING. Hold it to holster your weapon.
You can equip it as a primary, secondary, and equipment as well.
Oh, and it zooms in slightly (FOV 50) when you ADS with it. Works as a decent recon tool in my opinion.
