**_When dropping a radio from your inventory you will be able to Hack the facility with different options. Changing radio stations will change the possible hack. The hacks cooldown length is based on hack tiers (high, medium, low). Cooldowns of each tier will not interfere with each other. This means you can do multiple hacks at the same time if they are in different cooldown tiers. You will unlock new hacks and level up your current hacks based on how many kills you have._**
