Offline Tower Defense: AI War

Offline tower defense against a rogue AI. Build turrets, hold the lanes, survive endless waves. No WiFi, no internet, no timers. A rogue AI has broken containment and its viruses are already pouring down your lanes. You are the last firewall. Place turrets along both flanks, draft one upgrade out of three every level, and burn the swarm down before it chews through your gate. There is no game over screen. When the gate breaks you choose: fall back a few waves for free, or push straight on. The run only ends when you decide to stop. TRUE OFFLINE TOWER DEFENSE No WiFi, no internet, no login, no server queue. Every wave, every upgrade and every boss works in airplane mode. It is a single player offline game and your save lives on your device, so it plays the same on a commute, on a flight or in a dead zone. IDLE, AFK OR HANDS-ON The offline vault keeps mining coins while the app is closed. Come back to a payout, spend it on turrets and perks, and drop straight into the next wave. Play it as an idle AFK tower defense that earns while you are away, or grind the waves by hand. Both work. No energy, no lives, no countdown timers. THE ENEMY LEARNS This is not a static wave list. The swarm measures how fast you are killing it and scales to keep up. Lean too hard on one weapon and viruses start arriving immune to exactly that damage type, so a balanced arsenal beats a single maxed-out gun. Every ten waves a boss shows up to test the build you actually made. 48 VIRUSES, 6 DAMAGE ELEMENTS Physical, fire, ice, poison, lightning and corrosion, each with resistances, immunities and weak points. Armored runners, exploders that damage the gate when they die, shielded carriers, and adaptive types that go immune to whatever you are strongest at. Read the wave, pick the counter. WHAT YOU GET - Endless TD waves with themed rounds and a boss fight every 10 waves - One-of-three upgrade cards: a roguelite draft on every single level up - Weapon shop paid in coins, gate and global perks paid in chips - a real dual currency economy - Adaptive difficulty plus a counter-attack AI that re-weights the swarm against your strongest weapon - Offline vault that keeps piling up coins while you are away - Neon wireframe visuals tuned to stay smooth and easy on your battery - Portrait, one hand, no rotation - playable standing on a train - No forced ads between waves, no energy system, no paywall to reach wave 100 HOW TO PLAY 1.

FAQ Q: Does it really work with no internet? A: Yes. Install once and the whole game runs offline. Airplane mode, subway, plane, elevator, dead zone - every wave, boss and upgrade still works. No login, no account, no sign up. Q: Is it free? A: Free to download and free to play through. Rewarded ads are always optional and you can push as far as you like without watching a single one. Q: Will it run on an older phone? A: Yes. Lightweight neon wireframes instead of high poly models, and the frame rate is capped on purpose to save battery. Q: Do I have to pay to progress? A: No. Every turret, gate and global upgrade is bought with coins and chips you earn in game. Build your defense. Outlast the AI. How far can you push the firewall?
