On the Nature of a Sentry: A Comprehensive Guide on the Sentry's Biology and its Place in the Community

Thanks to everyone from our discussion about sentries!


Sentries are a special kind of device that mimic a gim. They have rapidly evolved over time.



The sentries originated from chemical supreme, a highly dangerous chemical that caused the growth of the original plant sentries, which had a wooden wand as a weapon. They had two appearances, pink and green.

The Robotic Age of Sentries:

Some sentries found that it was better to change their appearance to a more robotic look, and sentries then gained the ability to take on other weapons.

The Device Age of Sentries:

Sentries were being tamed, and now could join the side of a gim's team. New technologies were developed with devices to transport the sentry.

The Aggressive Age of sentries:

Sentries suddenly dropped compatibility with other devices and could not move, investing more of their time into combat. Sentries originally made friendly to all gim's and others broke free from their device systems.

The New Age of sentries:

Sentries developed new technology to imitate a gim even better, being almost identical, and being able to transform at any given time.

Different sentry sub-species

Green plant species:

The green plant species are a species of sentry that have evolved to reproduce at high rates. Because of this the green plant species are generally much weaker then their pink counter parts. Very few of this species decided to go the robotic route. Their weapon of choice is a wooden wand.

Pink plant species:

The Pink plant species are a species of sentry that have evolved to be strong. Because of this they do not reproduce as quickly as their green counter parts. Many of this species decided to go the robotic route. Like the green plants, they mainly use wooden wands.

Robot species:

With the discovery of a unknown vessel the sentries discovered that they could change their own appearance. This led to the creation of the robot sentries. Robot sentries have adapted to focus more on shields rather then health. These sentries have a much more broad capability with weapons, however they still mainly specialize with the zapper. They also have a very broad range of reproduction and health/shield + damage.

I converted the details sections of the guide into headers

Can someone add in unarmed sentries?

I could but I don’t know if I should edit it.

Feel free to edit this.

Should we add talking with sentry’s?

Now all we need are some funny sentry pictures.

:memo: 9

  • removed duplicate chapters
  • fix formating
  • remove unnessacary [quote] at the bottom
  • Link contains no content, so onebox was replaced

…Did someone say they need funny pictures? Would you like me to make them?


Can I make edit #10?

Simplifying the title to “Applications with Sentries”

Yes, I would definitely like to see them.

You can kinda do that with a zone by setting it so that weapons can’t be fired inside of that zone.

The sentry still has the weapon though.

With the patch of the sentry “bug”, does this stuff still work?

Not much anymore… Oof

@Jeffo, can you un-patch the sentries please?


Please do not ping him, it may seem disrespectful and he may not see it. Instead, send a PM to the moderators here and he will see it.


One of the discord channels is protesting… I think he’ll see that lol


It probably means Bring Back Sentry Interaction.
