Protect the Core. Enemies follow the path. If they reach the end, you lose Lives.

Waves do not start until you press START. After a wave ends, the next wave begins 15 seconds after the last enemy dies. Press START or SKIP to begin early.

When you SKIP, the next wave begins immediately. Use it to speed up runs.

Build on glowing tiles only. Select a turret to upgrade it up to III. Each tier changes visuals and stats, and you choose a mod each tier.

1x/2x/3x/4x affects everything time-based: movement, fire rates, projectile speed, DOT, and wave timers.

Enemies can have Armor (reduces Physical), Shields (absorbs Energy), Stealth, Flying, Regen, and more. Mix turret roles.
