of course we are using lethal weapons these are air soft guns looking credibly real and cost around a $1000.00 euros each. they only fire small plastic balls. but it still hurts. i got here as my 1st one and one more and i'm out. of all of them to all the other popular shooting games include laser tag and paint ball the bullets are still quite high velocity which is why we all wear goggles and you can't play until you're 18. the demand is huge here and knocked about alone the number of players has increased 10 fold since 2013.
