Perfect for fans of tower defense games looking for fresh gameplay mechanics. The merge system adds depth to traditional TD gameplay, requiring players to think carefully about resource management and tower placement.
Master Fireline: Merge Defense with these expert strategies:
1. Merge Strategically: Combine lower-level cannons to create more powerful versions. Prioritize merging cannons in key defensive positions.
2. Balance Your Defenses: Create a mix of fast-firing and high-damage cannons to handle different enemy types.
3. Upgrade Path Planning: Focus on upgrading cannons along critical paths where enemies concentrate.
4. Boss Battle Tactics: Save your strongest merged cannons for boss waves and position them where they can deal maximum damage.
5. Resource Management: Don't merge too early - sometimes multiple weaker cannons are better than one strong cannon against swarms.
