Tips & Tricks
- Upgrade your existing defenses before buying new onesโstronger individual towers often outperform spreading resources
- Position your highest-damage weapons where they cover the most ground against approaching zombie clusters.
- Don't spend all earnings immediately; save resources for critical moments when stronger waves arrive.
- Check your idle earnings regularly to reinvest them into permanent upgrades that persist between sessions.
