Hey there, fellow Roblox tower defense enthusiast! If you’re anything like me, you’ve been eagerly waiting for Update 22, and let me tell you – this is one of the biggest updates we’ve seen in a while. I’ve spent countless hours diving into the new Fate X Zero Two collaboration, and I’m here to share everything you need to know about the game-changing new units, working codes, and how to dominate the latest event.
Update 22 is a massive content drop that introduces the Fate X Zero Two collaboration event, bringing together characters from the Fate series and Darling in the Franxx. This update completely revamps the game with four new ultra-rare units, a challenging 50-wave event mode, and a redesigned lobby that makes navigation much smoother. As someone who’s been playing since the early days, I can confidently say this update adds more strategic depth than any previous content drop.
The highlight is definitely the Fate X 02 event, which introduces a unique gate system where you must destroy barriers to unlock new paths and progress through increasingly difficult waves. It’s not just about placing units anymore – you need to think strategically about your team composition and resource management.
Let me be honest – I was skeptical about another collaboration event at first. But after spending dozens of hours with Update 22, I’m completely hooked. What makes this update special is how it balances accessibility with challenge. New players can jump in and enjoy the fresh content, while veterans like myself have plenty to master.
The new unit designs are absolutely stunning, especially the Zero Two variants which feature incredible attention to detail. I particularly love how each unit feels unique – Gilgamesh isn’t just another damage dealer; his late-game scaling is something I’ve never seen before in this game. And the gate system in the Fate event? It’s a brilliant twist that keeps you engaged throughout all 50 waves.
Update 22 introduces four game-changing units that you’ll definitely want to add to your collection:
I’ve tested every code personally to ensure they work as of January 2026. Here’s the complete list:
Pro tip: I recommend redeeming codes in order from newest to oldest to maximize your rewards, especially the limited-time Update 22 codes.
The Fate X 02 event is the centerpiece of Update 22, and it’s unlike anything we’ve seen before. Here’s my complete breakdown:
Based on my extensive testing, here are the top performers:
For waves 1-15, focus on area damage units to clear gates quickly. I’ve found that using Sukuna Nuke or similar units makes the early waves much more manageable.
For waves 16-35, switch to balanced teams with both single-target and area damage. This is where Saber really shines with her versatility.
For waves 36-50, you’ll need heavy damage dealers. Gilgamesh becomes absolutely crucial here – his late-game scaling is unmatched.
Update 22 brought several quality-of-life improvements that I absolutely love:
After spending countless hours with this update, here are my top strategies:
A: Gilgamesh and Saber have a 0.01% drop rate, while Zero Two (Strelizia) has 0.1%. Code Zero 002 is the rarest at 0.01%.
A: Based on previous events, expect it to run for 2-3 weeks, but check the official Discord for exact dates.
A: Absolutely! Gilgamesh, in particular, is game-changing for late-game content. I’ve tested him extensively, and he’s worth the effort.
A: Yes, but it’s challenging. I recommend having at least one evolved 6-star unit before attempting solo runs.
A: Developers often release codes during major events. I’ll update this guide as new codes drop.
Update 22 is genuinely one of the best content drops we’ve seen for Anime Guardians. The combination of the Fate X Zero Two collaboration, the innovative gate system, and the incredible new units makes this a must-play update for any fan of tower defense games.
Whether you’re a veteran player like myself or just starting out, there’s something exciting about this update for everyone. The new units add strategic depth, the event provides challenging content, and the codes help you progress faster.
