Void_TD is a sci-fi tower defense game where you defend your base against waves of void-spawned enemies. Place towers on the grid, upgrade your defenses, and outlast 20 increasingly dangerous waves — culminating in a showdown with THE VOID, the ultimate boss. TOWERS Choose from 6 unique tower types and build your perfect loadout: - Laser Turret — fast-firing single-target beam - Plasma Cannon — area-of-effect splash damage - Void-Seeker — long-range precision strikes - Titan Mech — devastating heavy splash damage - Void Stunner — slows groups of enemies and weakens bosses - Tesla Tower — electric AoE with burn and stun upgrades Upgrade each tower up to level 3 for increased damage and range. Sell towers mid-wave to adapt your strategy on the fly. ENEMIES Face off against 6 enemy types, each with distinct abilities: - Scouts and Shades test your reaction speed - Tankers and Sentinels absorb punishment with raw HP and periodic shields - Heralds stun your towers as they pass - THE VOID enters with heavy armor that must be broken before you can finish it off Enemy strength scales with each wave — no two runs feel the same. THREE DIFFICULTY LEVELS - Normal — learn the ropes and master your strategy - Hard — 1.5x enemy HP, unlocked after beating the campaign - Insane — 2.5x HP and faster enemies, for those who want a real challenge ENDLESS MODE Beat the campaign to unlock Endless Mode, where waves are procedurally generated with exponential scaling. There is no final wave — just you, your towers, and the void. Compete against your own high score. CUSTOMIZE YOUR LOADOUT Equip up to 5 towers before each run. Earn coins from victories to unlock the Tesla Tower, buy cosmetic skins, and customize your towers with 9 color tints. Redeem codes for exclusive rewards.

A real RTS on your phone: 29 units, 75+ upgrades, an enemy AI that learns how you play — free, offline, nothing to buy. Global Ordnance: The Iron Fist is built in the spirit of the classic PC real-time strategy games of the late '90s — real units, hard counters, a front line that moves — and redesigned from the ground up for a touchscreen. The whole battlefield fits on one screen. No base to build, no map to drag: every decision is a combat decision. Research, deploy, push the line, and put a shell through the enemy HQ before it does the same to yours. YOU COMMAND. DIRECTLY. Units drop straight onto your side of the field while the fight is already on. Pick targets, focus fire, pull back. Two fingers grab every tank, three every vehicle, four every gun; double-tap takes every unit of one type. No menus mid-fight. FROM SCOUT CAR TO NUCLEAR STRIKE • The Ferret: $100, fast, fragile, first on the field • The Mammoth Tank: two barrels, crushes lines and keeps rolling • The Trident: three barrels, artillery range, lays mines as it moves • The Sniper Tank: never misses, fires first, dies if anything gets close • The Hammer Tank: one oversized gun, the highest HQ damage in the game • The Corsair and the Twin Bomber: four guns and twin rockets, or a long-range missile from beyond sight • The Apocalypse bomber and the V2 ballistic missile: when the ground game is not enough 29 units across armor, vehicles, aircraft and fixed defenses, every one with an in-game info card and a counter. UPGRADES THAT REWRITE A UNIT 75+ upgrades, researched while shells are still flying. A Medium Tank with the Grinder chews through wreckage and repairs its own hull. Uranium shells leave lingering radiation. Chaff, flash bombs and a radar scrambler blind the enemy's anti-air. Upgrades don't buff a unit — they change what it is. AMMO RUNS OUT. WRECKAGE PAYS. Kill-to-Earn: what you destroy funds what you build next. Ammo is finite, so supply trucks rearm and repair the front, lay anti-tank or nuclear mines, and the units that survive rank up and hit harder. THE ENEMY IS WATCHING The Adaptive AI tracks how you play and counters it. No inflated stats, no artificial accuracy, no scripted waves — it just plays smarter. Do well, and your best units become its priority targets. Keep your anti-air close. THE GROUND FIGHTS BACK Two battlefields: a green biome, and a snow biome with Thin Ice — frozen ground that holds a unit only so long. The heavier the tank, the faster it sinks. Send a Mammoth onto the wrong patch and it isn't coming back. THREE WAYS TO PLAY Classic matches. Timed Blitz: 1, 3 or 5 minutes, only HQ damage counts, turtling loses. Upkeep: every unit on the field costs you money for as long as it stands. FAIR BY DESIGN • Free. No in-app purchases, no premium tier, no pay-to-win • Plays offline — no account, no connection needed • 60+ achievements unlock skins and perks — earned by playing, never sold • Ads never interrupt a match: at most one after it, and none at all if you win • iPhone and iPad, with a dedicated large-screen layout • A 14-track metal soundtrack written for the game Much of how the game plays — the controls, the ad rule, the balance — came from RTS players on forums and social media. A new update most weeks, every one free and documented at awngames.com. Made by a two-person studio.
