Flyswatter in DOORS: Crucifix vs. a Gloombat Swarm

Updated 10.10.2026· Author: Mark K

Where to get it

Chewing behind a door in The Mines means Gloombats are in the next room. To get the badge, you need to anger them with light first, then pull out the Crucifix right before they strike. The badge is now called Bug Bomb; Flyswatter was its old name.

How to get it

Make it to The Mines: Gloombats can appear there when you open a door.
Hold a flashlight or another light source and turn it on.
The swarm will fly toward the light and attack you while it’s on.
When the swarm gets right up close, quickly switch to the Crucifix. The swarm will bunch up into a ball and disappear, and you’ll earn the badge.

How hard is it?

This badge is rare: about 9 out of 10,000 players who have ever entered DOORS have earned it. The tricky part is the timing. Pull out the Crucifix too early, and the light goes out and the swarm calms down. Too late, and they’re already biting.

Tip

I keep the Crucifix in a slot next to my light and use it as soon as the buzzing gets loud. There’s no time to think.

Why the swarm won’t notice you without light

Gloombats won’t bother you if you don’t have an active light source. An unlit flashlight or Lighter in your hand won’t anger them. Glowsticks and the Laser Pointer won’t trigger an attack either.

That makes getting the badge tricky. You need a real light source, or the swarm has no reason to get angry at you.

How to hear the swarm coming

The swarm usually flies in a group of five or more. You can recognize it by its loud, metallic buzzing. If you go into the next room, the swarm will follow as long as it can sense your light.

No luck the first time? No big deal. Gloombats disappear on their own after about 2 minutes. When that happens, I turn off the light and try again with the next swarm.

Don’t lose your second Crucifix

There’s a bug with banishing Gloombats. If you picked up a second Crucifix, it may disappear from your inventory along with the first one. I’d use the Crucifix on the swarm when you don’t have a second one in your pocket.

You don’t need to turn on the Straplight to banish them.
