The Climate Trail is a "good, realistic, and sobering" free game about the post-apocalyptic world we face if we continue on our current path. The Climate Trail uses the play style of the most popular educational game ever released, The Oregon Trail (65 million copies sold). The tipping point we are now at with climate change inspired its creation. The Climate Trail is an entirely free game with no advertising about climate refugees fleeing ever-worsening conditions after inaction on climate has rendered much of the USA (and the world) uninhabitable. The game combines the simulation game of the journey north with visual novel elements where characters reveal how and why this climate apocalypse unfolded. The game is available for the iPhone, iPad, Android, Mac, PC and Linux systems.
