What it is
Waves don't pause. Placement decides it. You build and upgrade fortifications, pick units that hit hard at the range you need, and reposition when tougher foes walk through the gap you left open last round.
How a round works
Place a tower. Watch the path. Upgrade what covers the leak, survive the wave, and spend the payout on the unit type that actually slowed the last breach instead of a random new pad.
Tips
- Upgrade the tower covering the leak first.
- Mix a slow unit with a high-damage one on long paths.
- After a loss, change placement, not only upgrade levels.
