Undead Invasion drops you into a gritty side-scrolling battlefield where zombies never stop coming. You’re one of the last survivors, stuck in a collapsing world full of armored brutes, fast crawlers, and mutated monsters that get tougher each day. The goal is simple: stay alive, keep upgrading, and protect your base from anything that tries to break through. The game combines quick arena combat with strategic elements, so every run feels unique, and every mistake feels personal.
Each match takes place on a compact 2D arena where enemies pour in from both sides. You shoot, dodge, and rebuild while keeping an eye on your base’s health. The pace ramps up fast—early waves are warm-ups, but later days throw in zombies with helmets, shields, or armor that can tank heavy fire. You earn cash for clearing waves, which is spent on new weapons, repairs, or defensive upgrades. Survive the day, prepare for the next, and try not to let the pressure catch you off guard.
