It's a matter of conscience. There's no need to spend money on accumulating values, and there's no need to watch extra ads.

Summarize

Whatever is useful in the first few chapters, the few towers in the first row are enough. Blocking roads and taking detours will show off their magical powers (the most fun time).

After you beat the key tower carbon barrier (dice) (F Universe Defender) and enter the numerical era, the difficulty drops sharply. You can go back and replenish stars to gain skill points, or you can push all the way to quickly pass the level. (Just go hard, give it 6 stars, play one level and watch an ad once. In this way, after playing three or four levels, you can upgrade back to 3 energy and naturally return energy to the energy exploration team = ****. The income is enough and you don’t need to watch additional ads. )

The next step is to buy modules according to the chapters and pile up the values ​​(at F, the modules of the front tower take effect, but the modules of the back tower do not take effect, so the front tower uses the module with the best defense and durability, and the back tower uses modules that reduce attributes and reduce resource consumption). It basically doesn't break defenses, it's safe to attack casually, the spaceship is used as a bait, it doesn't block or go around, the crystal beam harvests, the main focus is short and fast.

Tower Strategy

Fishing: spaceship (isolate as much as possible to prevent AOE from affecting other towers), space defender, blood recovery tower, and shield recovery tower.

Against the group: Crystal Tower, calculate the distance (3 blocks), its special attack mode has ridiculously high dps against the sea of ​​monsters.

One-on-one: Beam tower, shield-breaking, high dps, cheap to unlock, complete quadra (except against octopus Trojan).

Auxiliary: Freezing tower defense, self-destruction and face riding (it can also reduce the HP of the octopus Trojan by a percentage), attack speed tower is given to the crystal tower F, the attack tower does not matter, and the armor-piercing tower is not needed.

It is enough to bring 7/8 towers to clear the level, and 5 towers are enough for the core point. The other towers are of no use. The numerical value is still not designed well. It is not unfair to say that the numerical game is a numerical game.

Key points

The first turning point is unlocking the crystal tower (from now on, the problem of the sea of ​​small monsters is gone, and you are qualified to stand in front of the sea of ​​self-destructing monsters.

The second turning point is to unlock the carbon barrier (dice, F space defender). From now on, the spaceship will not be blown up and you can fish. Enter the era of stacked values.

The third turning point is the emergence of the beam tower (from now on, the problem of elite monsters and crystal tower missing monsters is gone.

The fourth turning point is when the resource tree of the research institute is full and the range of the auxiliary tower becomes 5x5.

The difficulty is reduced a lot at each turn. Use these towers until you pass the level.

Threats

If there is no solution to move the tower, just use the value, resources, and repair the tower to see if he can move it faster or you can build it faster. (You can also use the one-time prop to block the ground so that he has no place to move, which is slightly more expensive.

There is no solution to banning healing. You just have to fight for the value to see if he can beat you with a wave of banning healing.

Self-explosion in the sea of ​​monsters and freezing crystal towers along the way.

A sea of ​​elite monsters, freezing beam towers along the way.

If the numerical value cannot withstand it, then you have to rely on the defense skill tree to make the last person invincible for 5 seconds before death, the skill to be invincible for 5 seconds, and the wall with the invincibility module to block the road.
