One Gun Guard (一炮当关; pinyin: Yī pào dāng guān) is a Brain Buster in Sky City in the Chinese version of Plants vs. Zombies 2. In it, the player controls a machine which fires lasers at the synchronized patterns of flying zombies. The goal is to gain enough points to pass the level, and in that sense, it is similar to Cannons Away, but it does not have a progress bar so the player can shoot as many zombies as they want and aim for the best moment for shooting the most zombies. The player will lose if they have no sun left.


There are three types of weapons;

  • A regular cannon that takes 25 sun to shoot. It has the highest attack but can only deal with one zombie at a time.
  • A laser cannon that costs 125 sun to use and pierces a line on the whole screen. It has lower attack than the regular cannon, but can take care of lots of zombies.
  • A homing cannon that uses 250 sun to use. It has even lower attack than the laser cannon and targets random zombies but will always land a hit.

The homing cannon is difficult to use and should not be used in most situations. Use the laser cannon to destroy massive swarms of weak zombies and the regular cannon to destroy single and powerful zombies such as Gargantuars.

Defeating zombies will earn you sun, so defeat as many zombies as possible. Take note that all Castle in the Sky special zombies appear in these levels and they take varying hits to kill. There is also no time limit as well, so think which way you can kill the most zombies for sun and points with the least amount of sun before you shoot. You will also encounter green Double-Cabin Aircraft Zombies which will enable your cannon to go on a rampage and shoot without spending sun. In later stages, the player can encounter Gargantuars which allow him to get a lot of sun and points if he defeats them. Since they have high toughness and appear alone, use the regular cannon to take care of them.

Remember your cannon spends sun continuously as you activate it, so do not open your cannon for an elongated period of time.
