Purify the World

In a world ravaged by pollution and overrun by zombies, your primary goal is to survive against all odds. Navigate through the devastated streets where danger lurks at every corner, as you encounter hordes of undead creatures. To secure your survival, you'll need to engage in the critical task of collecting and studying zombie DNA. This scientific endeavor is not just for understanding the enemy but also for crafting a vaccine that can cleanse the contaminated environment. With the vaccine in hand, you'll work tirelessly to purify the surface, making it habitable once again.

Amidst this chaos, collaboration is key. You'll need to forge alliances with the few remaining survivors, pooling your resources and knowledge to increase your chances of enduring this apocalyptic scenario. Together, you'll strategize, support each other, and strive to rebuild a semblance of civilization in a world that's been turned upside down. Remember, in this fight for survival, every step towards understanding the zombies and every effort to clean up the world brings you closer to reclaiming your future.
