How to play

  1. Choose a tower, then tap or click an empty pad beside the data channel to build it. Keyboard: 1–5 picks a tower, arrow keys move the cursor, Enter builds.
  2. Press Start wave. Enemies follow the channel to the AI core; each one that gets through costs core health.
  3. Destroyed threats pay credits. Select a tower to upgrade it twice or sell it.
  4. Send the next wave early for bonus credits, speed the game up to 3×, or pause at any time.
  5. Clear campaign stages to unlock new towers. Better results earn research cores for permanent upgrades.

Towers and threats

Laser fires fast, cheap bolts but struggles against armour. Firewall burns everything around it. Freeze slows enemies down. Pulse arcs lightning between targets and is especially good at stripping shields. Neural is slow and expensive but pierces armour from long range.

Threats include basic malware, fast bots, armoured bots that shrug off small hits, shielded worms whose shields recharge, and boss viruses. Mixing tower types works better than relying on one.

The daily challenge uses the same map, waves and three-tower set for everyone, resetting at 00:00 UTC. Progress and records are saved only in this browser. The game uses hand-written rules; no AI model runs while you play.
