About Zombie Siege Unblocked
Enjoy classic arcade nostalgia packed with high scores, fast action, and responsive controls. The city has fallen to the undead and youre the last line of defense. Move with the left stick, auto-fire when zombies get close, and punch through mutant hordes and towering zombie kings. Rescue trapped survivors to build your squad — a shield tank up front, a sharpshooter at your side, a medic in the back — and escort them to the safe zone. Kills drop medkits and bombs, bosses drop permanent upgrades, and 5 unlockable weapons grow with you. Fight across city streets, wild forests, and underground graveyards as the horde grows deadlier every level. How far can you survive?.
