Neon Defender is a fast, free tower-defense survival auto shooter. Build turrets, upgrade your ship, and hold back endless waves of glowing Zomboji creatures - solo, with friends, or against them.

⚔️ FIVE WAYS TO PLAY
• SURVIVAL - borderless deep space, endless escalating waves, one more run every time
• PLANET DEFENSE - guard a living world with its own hull integrity, orbital battery and planetary shield. Lose your ship and the fight goes on: your turrets keep firing until the planet falls
• ONLINE CO-OP - team up in real time, revive downed teammates, share the swarm
• PVP ARENAS - free-for-all or team matches, first to 10 kills, three hazard maps
• GALAXY VENTURE - a full space campaign: 44 star systems, hyperspace fuel to manage, alien races to hail, ally with or fight, derelicts to salvage, jump-gates, bounties, and a motherworld finale

BUILD YOUR DEFENCE
Ten turret types and space-grade barriers, each upgradeable mid-fight. Pin your favourites, chain tesla arcs through a crowd, drop venom fields, or wall off a lane and let the mortars work.

PROGRESS THAT STICKS
Level up an account that carries across every mode. Unlock builder skills on a five-tier skill tree, buy permanent perks, and collect ship hulls, trails, turret skins and emotes. Sign in with Google and your progress - including your whole campaign galaxy - follows you to any device.

A GALAXY THAT REACTS
Eight alien races with their own music, territories and grudges. Warm one up with quests and they fight beside you; ally with one and its rival cools on you. Liberate a world and the swarm may come back for it days later.

PLAYS YOUR WAY
Touch or keyboard. Colourblind-safe enemy tiers, reduced-motion support, adjustable stick size, and a full in-game help centre. No download needed to try it - play free in any browser at neondefender.web.app.
