Tips & Tricks for Urban Defense: Protocol Z To conquer all 100 waves, you need more than just firepower; you need a solid plan. Here are some pro strategies to help you dominate the leaderboard in this zombie defense challenge. Utilize Adjacency Bonuses: This is the most unique mechanic in the game. Placing identical turrets side-by-side unlocks massive damage boosts. Look for the blue outline for pairs and green outlines for clusters of three or more. Plan for Procedural Paths: Since every map section generates a random path, do not rely on a single layout. Adapt your choke points based on the terrain and obstacles like rivers or bridges. Balance Your Economy: Do not spend all your cash on cheap units early on. Save up for high-tier turrets like the Rail Gun to deal with armored zombie variants later in the game. Know Your Enemy: Different zombies have different weaknesses. Use Flame turrets for crowds and Rockets for the heavy armored units. The undead never sleep, and neither should your defenses. Can you survive until the very end and protect the city from total collapse? Once you have mastered the art of zombie extermination here, you can play free survival games to keep the adrenaline pumping. Good luck, commander!
