All devices have a built-in water-proof speaker. This allows for voice feedback to be given to the user. And it's not limited to anouncing 'hit', 'wound' or 'kill' either... The system has over 300 emulations from modern firearms like the P90 to sci-fi phasers, but also medieval spells, monster sounds...

The feedback can be customised in a number of ways

• You can assign a language to each device, so all feedback is going to the user in his own language. If you're catering to tourists, you can send out the instructions in English from your console, but the gaming gun will 'speak' the language of the user. Informing players about the drinks break was never easier, as this feature eliminates translation issues. 
• You can select to use mor child-friendly laser-tag terminology on the devices
• the audio level can be controlled for a higher volume outdoors, or a lower volume indoors.
