1 resources, that is, money, can be obtained mainly in three ways: 1 killing monsters, 2 selling and picking up things, and 3 rewarding after each wave of monsters. Don't talk about killing monsters; To sell things, I think everything except scrolls and mana should be sold (except that I later hit a bead that can slow down the monster's movement speed by 3S); As for the reward after each wave of monsters, I think you will get more rewards after killing monsters than letting a single monster escape (I just don't think I noticed it, nor did I notice it urgently, the monsters came out too fast).
2 formations
This is the most important thing to get through. At first, I put three-quarters of the freezing towers along the road (entrance), and then put one at every 10 cm to the portal, so as to slow down the monsters all the way so as to have enough time to destroy them. This really worked at first, and most monsters 1/3 were almost completely destroyed. However, there are several waves of very fierce monsters in the game (which will be introduced in detail later), either with extremely thick skin or amazing speed, which can't be stopped at all. The worst wave actually rushed out of nearly 60 monsters! From 80 to 20.
After dozens of failures, I found that the firepower should not be too scattered. Many monsters let him escape because his blood was running out. So I played it again and chose three points according to the terrain. Main attack point one: the door. Main attack point 2: "throat". Main attack point 3: "thigh". Note that the tower below has gone up, and the last three items have also gone up, but the first item has not moved (note: I can't post maps, so I guess what I said is a bit abstract and difficult to understand).
Apart from these points, I didn't put any towers on the road. The same resources, changing the location will bring completely different results. There are still more than 30 places after the final clearance.
3. Heroes (super important)
No matter how well the formation above is arranged, it is not enough to pass the customs (admire the designer of this map again)
Among the three heroes, I like to use the second Anna MM best. The four skills are all sharp weapons against fierce enemies except meteor shower.
At the beginning of the game, first build an arrow tower at a throat, then build five in a row (take that to the door, six), and then stare at the money. You will be a hero when you reach 50. Usually, a monster breaks through your defense. Before upgrading the freezing magic, destroy it with freezing. Then nothing is repaired, and it is up to the hero to catch up and stop one or two waves of monsters. When the money arrives in 60 yuan, the sheep-headed workers will be dispatched immediately, and the elf workers will rest at the door (so as to find it later). Can't repair water towers, fire towers, electric towers, only ice towers. First put two at the nearest door, then take down the two arrow towers in turn and fix them into ice. As shown in the above figure, the layout of the ice tower is completed in time.
(I have to mention the upgrade of the ice tower here. The level must be repaired before upgrading. Why? Because once the tower is upgraded, it will be expensive to maintain (20 for the first time and 25 for the second time). After the ice tower is built, the sheep head can come back to rest (permanently).
In the mid-term, the ice tower will come back to life, and it will face the first wave of super monster "Hydra", which is actually a hydra, but this guy is very thick-skinned, so it is best to let the ice tower rise to the second level, otherwise it will be unstoppable. Before that, MM's skills must be frozen first, and then the magic ball. Then, smash it hard, and don't think about leaving magic for the next wave of monsters.
Then the dead rider, blade master, hill, hunter and some miscellaneous soldiers rushed over. It is best to freeze their heroes before they enter the gate, and then build nothing until the money reaches 300. As soon as you have money (40G is a unit), you will build/upgrade the skull tower in turn at each stronghold until three main attack points are arranged.
Later, the most BT monsters will appear soon, and they are all transferred instantly! The freezing tower has lost its function. Be sure to calm down, there is a lot of space under the third stronghold and beside the collar, and build the skull tower here immediately! Of course, we should also supplement the strengthening towers and strive to strengthen each skeleton tower. Don't worry about other places, it's basically a waste.
There is another skill in hero operation. Usually you just play in front of the monsters and take time to put a magic ball on the road. Don't worry about anything when you meet a fierce monster. Don't leave anything you can, even if you attack a meteor shower with only 15. (End)
Many units in the game have not studied it carefully. For example, the poison tower can also slow down the movement, but I am useless. I wonder if anyone has passed the test with other heroes or different formations?
I wonder if any other experts have developed any simple and convenient methods after customs clearance. Ha ha.
