Vector Defense

VECTOR DEFENSE — a neon, vector-style tower defense that runs entirely in your browser, in a single HTML file. No installs, no accounts. Hold a hero card to inspect it, drag it onto the grid to build, and hold the line.

Modes

• Campaign — 12 missions across 3 acts on a constellation map, with briefings from LUMA (an animated android storyteller), 1–3 star ratings, and heroes unlocked as you progress — ending in a showdown with the OVERMIND PRIME.
• Quick Play — pick your battlefield and a custom hero line-up, then survive 20 waves and into endless.
• Daily Challenge — one seeded run for everyone each day with a special rule: SOLO (one hero only), STRIKE TEAM (fixed squad), LIMITED POOL, or a HANDICAP. Clear it for bonus rewards and chase your best wave.

Build your squad

• 9 distinct heroes — archer, frost, cannon, tesla, sniper, a support aura, a field medic, an acid-pool alchemist, and a knockback bulwark — each with two specialization branches and veterancy ranks.
• A pre-match line-up: drag heroes between the pool and your dock to build and arrange a capped squad.
• Structures — a credit-generating REACTOR and a devastating one-per-match BASTION.
• Active abilities (Orbital Strike, Frost Nova, Overdrive) and relic drafts after every boss.

Hold the line against 11 enemy types with damage-type resistances, gold-crowned elites, and 3 distinct bosses.

Earn & customize — a persistent Commander rank, plus a cores shop of grid themes, hero skins, and kill effects (pure cosmetics, no pay-to-win).

Made for phones too — drag-to-place touch controls, auto-rotation, and an installable offline PWA.

Hand-built as a single HTML file with HTML5 Canvas + WebAudio — no engine, no dependencies.
