Final Swarm worlds — Starter, Jungle, and Mythicals progression

Final Swarm exposes three named worlds and a Mythicals✨ chest rarity that sits above Epic. The worlds are the long-term progression path; the Mythicals chest tier is the loot upgrade that the worlds unlock. This page walks through every world, the title-suffix history, and how to reach each world from the Lobby.

The three named worlds

The Starter world is the original arena, the original weapon pool, and the original chest tier set. Jungle was added in 2026 as a new map with a Jungle-specific enemy roster and Jungle-themed end-of-run rewards. The Mythicals✨ drop event is the latest expansion and adds a Mythical rarity above Epic to the chest loot table — it does not introduce a new map; it adds a new rarity tier to chests opened in any world.

Title-suffix history

Evolution Studio Games publishes the current title suffix instead of a numeric version. The history:

If you see the title suffix change in your Roblox library without a numeric version bump, the title suffix is the only public version signal. No semantic version number is published.

How to reach each world

After you clear the 6-wave tutorial and beat the tutorial boss, step through the portal into the Lobby. The world-select screen lists the three worlds:

1. Starter — open the Starter world from the world-select tile.
2. Jungle — open the Jungle world from the world-select tile; Jungle-specific enemies and end-of-run rewards.
3. Mythicals✨ — Mythicals is not a separate world tile; it is the current suffix on the existing worlds, signaling that Mythical chests can drop from chest rolls opened in any world.

Mythicals chest rarity

The Mythicals✨ update adds a fourth tier above Epic on the chest loot ladder. The expected Keys per opened chest tier is:

• Wooden ~68.5 Keys
• Rare ~130.5 Keys
• Epic ~261.25 Keys
• Mythical ~480 Keys

The Mythical chest drop is the only path to the Mythical-tier Jungle weapon. The Mythical tier has not yet been confirmed to drop from any specific boss or wave — Evolution Studio Games does not publish per-tier drop rates. Treat the chest EV numbers above as player-entered scenarios in the optimizer and verify with your own observed drop rates.

Why the world progression matters for the Skill Tree economy

Each world pushes the wave ceiling higher and unlocks longer Keys runs. The Starter world is the easiest and the fastest way to bank Damage and Max Health ranks. Jungle rewards more Keys per minute but introduces a Jungle-specific enemy roster that requires Speed and Pickup Range ranks banked first. The Mythicals✨ chest rarity is the only path to Mythical-tier weapons and Mythical-rarity gear — it does not change the wave progression, only the chest drops.

Why Jungle is harder than Starter

Jungle introduces a Jungle-specific enemy roster with higher per-enemy HP. Players who attempt Jungle before banking Damage and Max Health ranks die at the Wave 8 boss inflection. The recommended progression is: Starter → bank Damage, Max Health, Defense → Jungle → bank Player Speed, Pickup Range → Mythicals chest farming → bank Attack Range and Luck.
