Zombie Invasion Calculator

This calculator relies on modified compartmental epidemic models (similar to SIR frameworks) adapted for supernatural survival dynamics. The core progression factors in initial population counts (Initial Humans and Initial Zombies), adjusted continuously by variables such as Attack Frequency, Human Conversion Rate, and Zombie Resurrection Rate. Defense and offense are quantified via Human Defense Stance and Human Fighting Skills, which mitigate incoming casualties, while Zombie Speed and Starvation Rate determine the attrition of the undead horde over extended timelines. The ultimate outputs estimate Remaining People, Remaining Zombies, and whether the timeline results in human survival or complete undead dominance.

Imagine a town facing a sudden outbreak with 1,000 Initial Humans and 50 Initial Zombies. Suppose the Zombie Speed is moderate, the Human Conversion Rate is 80% upon attack, and the survivors adopt a fortified Human Defense Stance paired with intermediate Human Fighting Skills. With an Attack Frequency of twice daily and a moderate Zombie Starvation Rate, the simulation processes these iterative loops. Over a simulated 30-day period, the model tracks the depletion of the human ranks versus the elimination and starvation of the undead, ultimately revealing whether humanity stabilizes the region or gets completely overrun.

To get the most out of your simulation scenarios, test extreme values to understand population tipping points. Raising the Human Defense Stance while keeping fighting skills low highlights the value of fortifications over direct combat. Similarly, tweaking the Zombie Resurrection Rate shows just how critical containment is during the early phases of any outbreak.
