Pirate harbor's 10th day and 5th day game form is similar. The system uses the conveyor belt to select the plants for the player. In fact, in this level, the player can be clearly familiar with the functions and uses of the new plants. There will be the following plants in this pass: coconut cannons (cooling time is required after the cannons are fired), three rows of shooters, spring beans (water grass phase in the function and plant war zombie 1, which can bounce plants directly back into the water for second killing), ground thorns and fire dragon grass, and players will get three energy beans at the beginning of the game.
1. The key point of the game is the ingenious placement of plants, such as three rows of shooters, fire dragon grass and other attack plants should be placed together, coconut cannons are often placed in the last row to fight for cooling time. Fire dragon grass can erupt fire, but does not support long-distance eruption. Players are advised to place fire dragon grass at the junction of deck and ground. Spring beans are usually placed around the water surface, such as beside the fault deck. So the order of placement from left to right is: coconut cannons, three rows of shooters, pitaya, spring beans and ground thorn.
2. After the start of the game, plants are placed in the order mentioned above. It should be noted that spring beans are placed in front of the fire dragon grass. On the one hand, spring beans can destroy a zombie first, and on the other hand, fire dragon grass can erupt fire to destroy the zombies behind. The power of fire dragon grass is no less than that of three row shooters, but it needs players to put in the right position.
3. Coconut cannons are usually used when the plants in front of them can't resist the zombie tide. In the later stage of the game, there will be more and more three rows of shooters and pitaya. At this time, concentrate your firepower and put these attack plants in the middle three rows. The defense positions in front of them are all given up to spikes and spring beans. Players can also use energy beans for powerful strafe when necessary.
