It's okay, there are 15 sirens to choose from, most of which are good however there are about 3 or 4 "Joke" sirens. E.G. Clown horn siren, as much as I understand that some people may want to go to emergencies with a clown siren blaring out as funny as it is, I would rather have joke sirens provided in the base game rather than the DLC. For me, I want a bit more choice of sirens for £4.30
