1. Opening strategy : Due to the tight opening space, priority is given to placing rocket turrets in the upper left corner area.
2. Fire control : In the first two waves, try to use rocket turrets to destroy monsters. At the same time, place electric towers in the lower right corner as assistance. Remove the central obstacle to obtain gold coins.
3. Gold coin investment : As gold coins accumulate, increase the priority of the rocket tower to full level. Don’t rush to build the right half of the area to ensure sufficient resources on the left side.
4. Multi-target attack : Use the bowling tower in the middle and late stages. One attack can destroy multiple enemies and improve efficiency.
5. Comprehensive defense :
-Right strategy : mainly rely on electric shock tower to provide continuous damage.
-Left core : Radar and rocket combination form a solid defense line.
Summarize:
With careful planning and timely upgrades, you will be able to successfully pass Level 21 of Defending Carrot 4 Apo and the Magic Treasure. Remember to use different tower defenses flexibly to ensure that every inch of land is used effectively.
