Last updated: 2026-06-18

Steps

1. Enter the map and claim an available base by walking through its door — choose flat areas close to spawn for compact defense
2. Upgrade your Door first — every upgrade increases HP and unlocks higher building tiers. This is your #1 priority
3. Upgrade the Money Printer (auto-spawns center of base) — your primary in-match economy source
4. Place 1 economy unit + 1 attack tower near the door — start with Vault/Gold Mine + Gun Turret/Cannon
5. All units lock position once placed — plan placement carefully, cluster near the door for maximum coverage
6. Use the Repair button when the boss attacks your door — manage cooldown timing to prevent breaches
7. Prioritize upgrading existing units over placing new ones — one maxed tower outperforms four weak ones
8. Split early budget 50/50 between economy and defense — neglecting either side causes failure

• Unit placement is permanent — think before you place, cluster firepower near the door
