Patch Notes 1.20

Webley & The Colosseum

October 2026

Hey everyone, Guigz here. Patch 1.20 is one we’ve been genuinely excited about for a while, and it feels great to finally get it into your hands.

This update marks the start of the Halloween season, but beyond the spooky vibes, it’s really about something bigger. With Webley joining the roster, we’re continuing to push in a direction we really believe in: heroes with abilities that actually change how you build your lineup. The goal over time is to make the meta feel alive, where a unit you once dismissed suddenly becomes essential depending on what you’re facing. We want every hero to have a moment, and we want you to always have a reason to experiment.

On the competitive side, we know our most dedicated players have been looking for more to sink their teeth into. Colosseum is our answer to that. A seasonal leaderboard for the best players, with rewards that mean something and a structure designed to keep things fresh season after season. But it’s not just for the elite, we want every new player to look at the leaderboard and feel like it’s something worth climbing. The more seasonal the game becomes, the easier it is to jump in, find your footing, and feel like you belong.

There’s a lot in this one. Let’s get into it.

New Hero · New Battle Pass

Meet Webley

Webley
Webley

Engineer Tarantula

A spider engineer who spins webs across your castle walls, reinforcing every brick in her column. As long as she lives, her walls hold. The moment she falls, so does everything she was holding together.

🕸️
Reinforced walls
Webley’s webs increase the material resistance of every wall in her column, making them much harder to destroy while she’s alive.

💀
Kill her, strip the buff
The reinforcement is visible to both players. Focus-fire her and the walls she was holding collapse instantly.

🏰
Walls that defy gravity
Reinforced walls hold their position even when separated from the castle base, until Webley dies.

🧱
Visible to everyone
The web overlay on reinforced walls is visible to both players from the very start of the match, telegraphing the threat clearly.
