A campy, crazy pixelart zombie apocalypse arcade sim where you're the bad guy. Drop your virus and spread it across the globe while you unlock a whole horde of bizarre undead to do your bidding.
The objective is to spread your zombie virus and wipe out all of humanity. The game's world map divides into different regions and continents. You start in one region and must strategically infect and destroy each area to progress to new continents. As more regions fall, human defenses and countermeasures rapidly escalate in difficulty.
At the core is managing and upgrading your zombie horde. You can unlock and "craft" over 35 unique zombie types, each with distinct abilities and strengths. These range from common "walking dead" to exotic mutations like alien parasites and yetis. You must carefully choose which zombies to deploy based on each level's challenges. Zombies have limited "lifespan" timers, so you must strategically spawn them to maximize destruction before they "rot away". Upgrading zombie abilities through a skill tree system makes your undead forces progressively more powerful.
Levels task you with infecting and destroying a set number of human targets within a time limit. Early levels are relatively simple, but difficulty spikes as humans deploy advanced defenses and countermeasures. Key challenges include avoiding "Zombie Intervention Tactics" (Z.I.T.) units, surviving powerful boss encounters, and racing against the development of a virus cure. You must use a combination of zombie spawns, environmental traps, and special abilities to overcome these challenges and progress.
The game features substantial customization and replayability. You can unlock new zombies, upgrade abilities, and toggle gameplay modifiers to dramatically alter difficulty and playstyle. Randomized events, enemy placements, and level layouts ensure each run is unique, providing an addictive "one more try" loop.
