MADE BY KIDS, FOR KIDS Robot Siege was designed and built by two brothers — ages 11 and 12 — for players who love tower defense games packed with progression and features. They built the game they always wanted to play. Now it's your turn to hold the line. Robot Siege is a fast, tactical tower defense game. Robots march along the road toward your base — it's on you to stop them. Place and upgrade towers, line up the perfect crossfire, and hold the line across waves that keep ramping up. FIVE DISTINCT TOWERS • Trooper — reliable rifle fire, the backbone of any defense • Sniper — high single-target damage from way downrange • Flamethrower — cone AoE that melts tightly-packed swarms • Wizard — equip up to 3 spells and slow enemies with a passive aura • Commander-in-Chief — a unique hero unit that buffs every nearby Trooper THREE BATTLEFIELDS • City — classic streets • Beach — ocean blocks one flank, +20% token bonus • Space — activate platforms to open new tower spots, +50% bonus DEEP PROGRESSION • Level up, earn tokens, and unlock permanent upgrades in the Education Center • Research Wizard spells — Eyesight, Speed Up, Heavy Bullets, Road Fire, Slow Aura • Collect power-ups by rarity (Common → Legendary) and build your loadout • Four difficulties, from Easy to brutal Hardcore Drag to place, tap to upgrade, and outsmart Robots, fast ScoutBots, and armored TankBots. No internet required — play anywhere. Robot Siege is free to play. Optional in-app purchases are available for token packs and convenience unlocks. No ads. Plays fully offline, anywhere. Built by kids, for kids — and for anyone who loves a deep tower defense challenge.
