About 3T22A's Siren Model Testing (UPDATE!)
Welcome to 3T22A's Siren Model Testing! Here you will find all my private siren models which I've been working on for over 3 or 4 years, with lot of passion. There are some rare sirens which you can find on my country and I did some models of them, and some familiar sirens which sometime I added on 3T22 Alarm System but I removed those back. The aim of this game is really simple: Test all the sirens and have fun with it! The game's max player per server is one, and the rank of HD Admin for every player is Admin, so feel free to do whatever you want in the game, so have fun with it and the sirens! I hope you can have fun, and enjoy the game like as I did when I was editing my projects and making this really simple game, keep the sirens running on! I also added the suggestion system like on 3T22 Alarm System, so you can suggest me stuff to add!
