I was wondering all the equipment that there is in the game. One thing that surviving game needs is walkie-talkies. I know there is TS and so on but that is for pre-formed groups. It could be cool if you could find walkie-talkie or other communication equipment from the map and the trying to contact other survivors through the channels. In best case scenario you can try to call rescuers to help you escaping from the building where you are being pinned by horde of zombies. In worst case scenario you give your position to the rotten eggs out there and get killed/robbed. I don't think this would even be hard to implement because there is also voice communication in the game. So just if player has active communication device activated other players with the active communication device can hear him. There can also be different channels, maximum distance to signal to travel, addons like headset, etc. Comment what you like about the idea...
