Vigilantes is a neo noir turn based, tactical RPG. Alpha 10 is the official version for the upcoming Kickstarter and Greenlight campaigns. It features 2-3 hours of gameplay over 9 missions. The current version of Vigilantes is considerably more feature and content rich and can be found on Steam.
This is a much older version of Vigilantes, which will give you an idea of gameplay, but doesn't offer a very good representation of the current state of the game. The most recent version of Vigilantes is vastly more feature rich, has much more content and polish, and can be found here on Steam.
