Early Access to Grass Simulator is now available on Steam, though one might suspect some non-simulated grass may have been involved in thinking this one up. The game involves shooting cows with a revolver, though there is also a Grass Simulation Mode which fulfils the title's promise. Here's a bit on the more action-packed Classic Mode: "You play as Garry Rambler, a rogue mercenary that escaped from hell who has sworn to take revenge upon the illusive cows that lurk among the shadows whom murdered his family, stuck in a purgatory filled with nothing but cows, grass and more cows. Only equipped with his moustache, cliché 80's mullet and magnum revolver; the exact revolver he used to kill the legendary cow god that ordered his family to be executed, he must fend for himself in a cruel, unforgiving dimension."
