Reactor Defense: TD

A rogue AI is sending machines to seize your reactor core. You have turrets, scrap, and your wits. Hold the line.

Reactor Defense is a fast, deep tower-defense game built for players who think a few waves ahead. Place and upgrade twelve distinct turret types across an open grid, read the enemy's adaptations, and decide whether to bank scrap for what's coming — or spend it now and pray your wall holds.

▶ TWELVE TURRET TYPES — EVOLVE THEM
Gunners, cannons, mortars, cryo-frost, chain-lightning arc, beam lances, warp, anti-air flak, corrosion, and support auras. Level them up, then unlock evolutions that transform your favorites into signature weapons — and push far enough to awaken their ultimate abilities.

▶ AN AI THAT LEARNS YOUR DEFENSE
The rogue AI reads your board every wave and builds the answer to it. Lean on splash damage and fast swarms outrun the blast. Stack single-target and armored titans soak it. Play it perfectly balanced and it finds the thinnest stretch of your coverage and floods it. Then it escalates: it sends upgraded attackers and new types that challenge any defense. You don't win by finding the optimal build — you win by adapting faster than it does, and no two runs hand you the same problem.

▶ THE SURGE — A BONUS WAVE TESTS YOUR LAYOUT
Deep runs earn Surge rounds: your towers redeploy on a strange map and the difficulty climbs faster than you can rebuild. Survive to bank bonus scrap and rare Field Kits — one-shot superweapons.

▶ EARN YOUR WAY FORWARD
Every run banks Mastery XP. Unlock evolutions, permanent upgrades, and new maps — an eight-map ladder that opens as your best wave climbs. Daily challenge runs and trophies for the completionists.

▶ BUILT TO RESPECT YOU
- Plays fully OFFLINE — no connection required
- Progress saves automatically
- No ads, no in-app purchases, no pay-to-win — buy turrets with skill, not your wallet

Think fast. Build smart. Defend the reactor.
