Description

The Png Bot4 was an enemy that appeared in Headache Headquarters, replacing the Breaker4. Currently, it only appears when the Brain Rot modifier is activated in Sandbox mode, replacing every modern Breaker4 variant, or with its Logbook. It has a high amount of health and defense, though it only has an average speed. Additionally, it spawns a Png Bot3 upon death, which has less health and defense but was faster.

Appearance

The Png Bot4 is a two-dimensional enemy that had multiple appearances. All of them are various images of cats, some of them being memes and other images of the developer's cats.

Headache Headquarters Strategy

As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in Headache Headquarters is listed instead.

• High DPS towers, like the Minigunner, Accelerator, Pursuit or Engineer are recommended against this.
  • The Commander and DJ Booth can be useful at boosting their firerate and range respectively.
• As this enemy spawns in hordes, towers that can damage multiple enemies at once, such as the Shotgunner and Pyromancer, can be useful.
• As its quite fast, stalling towers like the Electroshocker, Brawler, Cryomancer or Freezer can be quite useful.
  • These towers are especially useful as they can also drop its defense.
