Math Siege: Zombie Defense is a fast, brainy 3D tower-defense shooter where knowledge is your greatest weapon. The undead are pouring out of a dimensional rift — and the only way to fund your arsenal is to SOLVE MATH.

⚔️ DEFEND THE CASTLE
Hold the line through 23 escalating waves of zombies. Run, jump, aim and blast your way through hordes of Runners, hulking Tanks, loot-dropping Baggers, and terrifying Bosses that storm the field every 5th wave.

🧮 MATH IS YOUR ECONOMY
This is tower defense with a twist: there is no gold — there is GENIUS. Step into a shop, take on a timed math challenge, and turn correct answers into firepower.
The better you calculate, the stronger you get. Perfect for players who love a mental workout with their action.

🛒 FOUR SHOPS, ENDLESS STRATEGY
• Ammo Depot — poison, piercing and explosive ammo mods, plus RPG rockets
• The Armory — unlock 7 weapons: Pistol, SMG, Shotgun, Rifle, Plasma, RPG, Laser
• Castle Defenses — deploy wooden barricades, auto turrets and patrol soldiers
• Castle Health — repair your fortress before the next assault

🏰 PLACE YOUR DEFENSES
Buy a turret, soldier or barricade, then aim and place it exactly where the horde will hit hardest. Build a killbox and watch the lane light up.

🌀 CROSS THE PORTAL
Survive to Wave 21 and the dimensional portal roars to life. Step through and fight on in the neon-soaked CYBER WORLD — a whole new look for the battlefield.

🌦️ A LIVING BATTLEFIELD
Day turns to night. Summer turns to winter. Rain, snow and glowing lanterns set the mood as the sky shifts around you. Five camera modes (Isometric, Top-Down, Wide, Third-Person Follow and First-Person) let you fight your way.

🏆 HALL OF FAME
Climb three leaderboards — most Waves survived, most Kills, and most Math Solved.
Compete to prove you are the smartest survivor of them all.
