How to play UFO in the cat fight

1, first of all, brush out a good tower group. Frozen stars and radars are essential, as are rockets and multiple arrows. The plane stopped at about 25 waves.

2, when playing UFO, you must reduce the damage, mainly relying on radar attacks. There is no need to build a tower for the underworld in the early stage. There's no need to keep it. You mainly play UFO. Build a big tower and several first-class buildings around it, and spread them out. The flying saucer is likely to suck the small tower away. It can make a lot of money. The first flying saucer is easy to fight, the second one needs to build more towers, and the third one deliberately lets the radish die. Then when it comes back to life, the attack speed of all buf towers will increase, and the flying saucer will be quickly destroyed by this.

3. Buy more props and use money and minerals in advance.
