Survive The Swarm Pet Eggs: Essence, Codes & What Hatching Gives

Pet eggs in Survive The Swarm are bought with Essence, and hatching an egg gives you a pet with a permanent buff — extra damage, faster attack speed, or added knockback. If you want a pet now, the concrete path is: redeem the active codes CLASSES and LAUNCH for 25 Essence each, then use that Essence to buy an egg in-game and hatch it.

What eggs are for: Essence buys eggs that hatch into pets with permanent buffs

Essence is the currency spent on pet eggs. As Pro Game Guides puts it: "Essences are used to buy eggs in Survive The Swarm. Hatch the Eggs to get special pets that carry permanent buffs, such as damage, attack speed, or knockback." All Things How describes the same system: "Essence is spent on eggs, which hatch into pets carrying permanent buffs such as extra damage, faster attack speed, or added knockback."

Keep in mind that Essence is also used to buy classes, so you'll need to budget between the two.

How to get Essence now: active codes (September 2026)

Codes are the fastest way to build up the Essence needed for an egg before you purchase one.

These rewards are reported by third-party guides as of September 2026, so treat the amounts as a snapshot rather than a guarantee — check the reward text in-game when you redeem.

How to redeem codes for Essence

1. Launch Survive The Swarm on Roblox.
2. Tap the Store button on the right side of the screen to open the shop menu.
3. Scroll to the bottom of the Store window until you see the code entry field.
4. Type or paste a code into the Enter code field. Guides disagree on case sensitivity, so use the exact capitalization shown and avoid extra spaces.

Once you've claimed your Essence, check the current egg cost in-game, buy the egg, complete the hatch, and inspect the pet you received — its permanent buff will apply from then on. For a full breakdown of pet records and how each bonus compares, see the main pets page.
