The game is ‘a procedurally-generated first-person game of stealth and survival set in a very British world where robots hunt humans for sport.’ That means that you are put on an island with a British flavor, and have to fight for your life while being hunted by robots, and every game the environment will be different.
Sir, You Are Being Hunted was announced in March 2012, with a Kickstarter campaign later in the year to fund development. It’s an unusual game, with its 19th Century Britain-with-Victorian-Robots vibe, and it’s a tense humorous experience.
Big Robot says that version 1.0 is not the end of development for the game, with multiplayer and a customization tool for level generation planned.
