Retro Defense: Tower Defense

Build nine neon towers, pick a talent for each one, and survive bosses that tear your defense apart. No ads. No in-app purchases. Plays offline.

Retro Defense is a tower defense game set inside a synthwave megacity's network. Viruses pour out of the breach portal and follow the glowing lane to your core. Build towers beside the lane, upgrade them, and stop every hostile before it gets through.

27 TOWER TALENTS
Every tower upgrades twice. At Mk III you choose one of three talents, and its crown takes the talent's color. Turn a Vulcan into a lightning gun with Storm Rounds, set the lane on fire with Napalm missiles, freeze the grid with Blizzard, or fund your defense with a Bounty Drone. With 27 talents, no two defenses play the same.

BOSSES THAT BREAK THE MAP
Every fifth wave, a boss arrives and tears into your defense, and each sector hits harder. Spore.exe crash-lands and leaves a crater. A three-headed serpent rolls through the center of the grid. Siege walkers purge the towers at the lane corners. Kraken.net tears out your most valuable towers. In the final sector, half the map collapses and a colossal eye rises from the void. Wrecked towers are salvaged for credits, and you get a few seconds to rebuild before the boss wakes. During the fight, bosses jam your most valuable towers, and if a sector's final boss reaches the core, the run is over.

NINE TOWERS
• Vulcan: rapid-fire machine gun
• Rail: long-range sniper slug that ignores armor
• Prism: laser beam that heats up the longer it holds a target
• Hydra: homing missile volleys with splash damage
• Cryo: freezing pulse that slows everything nearby
• Arc: lightning that jumps between enemies
• Nova: shockwave that hits everything in range
• Relay: boosts the fire rate and range of neighboring towers
• Miner: earns credits at the end of every wave

FOUR ABILITIES
EMP stuns the whole grid. Lance calls an orbital strike where you tap. Overclock pushes every tower to max output. Firewall blocks and burns the lane.

FIVE SECTORS, HARD MODE AND ENDLESS
Neo-Grid, Data Stream, Mainframe, Cryo Vault and The Core each bring a new layout, new threats and two bosses. Clear them all to unlock Hard mode, with faster regular enemies, tougher bosses, a smaller core and 1.5× score. Then see how long you last in Overflow, the endless mode.

SANDBOX
Practice on any map with infinite credits and a spawn panel for every enemy and boss. Tower panels show damage per second, so you can test talents side by side.

KNOW YOUR ENEMY
Every threat you meet is logged in the Threat Database. Destroy enough of one to analyze its tactics, then keep going to exploit it for bonus damage.

GLOBAL LEADERBOARDS
Every sector and the endless mode has its own Game Center leaderboard.

FEEL THE FIGHT
Haptics let you feel every build, boss impact and core hit, plus the fire of whichever tower you have selected. One setting keeps them to the essentials, and Battery mode keeps long sessions cool.
