Siren

The Siren is a gadget included with Creatures 3, which emits a loud sound when it is activated or when a signal is passed to it. When it is connected in an array of other agents, it passes on the signal exactly as it was, and emits a sound. The siren can only be heard if it is visible on screen to the player. It can be used in a DS-standalone world by downloading the DS Connective Agent Pack.
