Master the latest Universal Tower Defense Z update with our guide—best units, currency farming, extraction tips & more.

Jul 11, 2026

The latest update for Universal Tower Defense Z has dropped, bringing a flood of new content—secret units, mythics, boundless characters, and a complete shift in the meta. If you’re feeling overwhelmed, don’t worry. This universal tower defense z update guide breaks down everything you need to know: which units are worth your grind, how to farm rerolls and gems efficiently, and what to do as a beginner. Whether you’re just redeeming the Kimpachi code or aiming to dominate the extraction mode, we’ve got you covered.

What’s New in the Latest Update?

According to player reports and the official Universal Tower Defense Z community, this update is massive. It introduced:

  • 4 new boundless units
  • 9 new secret units
  • 2 new exclusives
  • 8 new mythics
  • The unrivaled “Grammy” (Grammy) – a top-tier meta unit

The update also added new raids, an extraction game mode, and revamped several older characters with balanced evolutions. The old Dragon Ball–based meta has been largely replaced by new synergistic teams, especially around Spider‑Man characters and Bleach units.

Best Units to Prioritize in This Update

Not all new units are created equal. Based on early community feedback and in‑game testing, here are the standout picks:

Unit Type How to Obtain Notes
Ichigo (Rage) Balanced evolution Ichigo’s raid (10% boss rush, 3% act 5); evolve with holo essence + 3 swords Easy to farm; evolution is straightforward; very strong for mid-game
Rukia (Ruka) Mythic (freeze / slow) Summon from banner; evolve via raid 400k damage, full AOE slow – excellent support crowd control
Spider‑Man Trio Extraction units Spider‑Man extraction game mode Synchro abilities; each can deal 1M+ damage; pair with Venom and Iron Man for devastating combos
Joker Extraction unit Joker extraction (harder than Spider‑Man) Very strong but time‑consuming to unlock
Grammy (Unrivaled) Unrivaled unit Banner (can be selected) Absolute meta; high damage and synergy
Kimpachi (Berserker) Legendary (beginner code) Redeem code or obtain from story With his beserker cleaver (5% drop from Hollow Moon legend stage), damage jumps 800%
Fern Support (beginner code) Redeem code Solid early‑game support; permanent code available

Note: Many of the new mythics (like the Persona units and summer capsule units) are considered underwhelming by the community. Focus on the extraction trio and Ichigo/Rukia for the best value.

Beginner’s Path: From Zero to Pro

If you’re just starting out, follow this step‑by‑step progression:

  1. Redeem permanent codes – Get Kimpachi and Fern immediately. They’ll carry you through early story stages.
  2. Farm Kimpachi’s cleaver – Go to Hollow Moon (legend stage) act three. Farm until you get his berserker cleaver (5% drop). It buffs his damage by 800%, making him a beast.
  3. Unlock Ichigo – Complete Ichigo’s raid. It’s the first raid and relatively easy. Aim for the 10% boss rush drop. Evolve him into Ichigo Rage using holo essence (buy from hollow shop) and three swords from the later raid.
  4. Build a solid team – Pair Ichigo (or evolved Rukia) with Kimpachi and Fern. This setup can handle most content up to the extraction mode.
  5. Dive into extraction – Use the Spider‑Man extraction mode. It’s easier than most think, especially with matchmaking. Farm the Spider‑Man trio.
Step Action Goal
1 Redeem codes (Kimpachi, Fern) Strong early units
2 Farm Hollow Moon legend stage for cleaver Kimpachi damage boost
3 Complete Ichigo’s raid, evolve Ichigo Mid‑game powerhouse
4 Obtain Rukia from banner and evolve Crowd control / freeze
5 Farm Spider‑Man extraction End‑game meta team

How to Farm Currency Efficiently

This update offers multiple ways to collect rerolls, gems, gold, and universal fragments. Here’s the best approach based on player experience:

Universal Gems & Fragments

These drop from almost every stage. The most efficient method is AFK farming any stage you can clear quickly. The Granotica raid is especially good for universal gems, according to community reports.

Rerolls (Trait Rerolls / “Reroll Currency”)

Rerolls are critical for rolling good traits on your units. Here’s a weekly breakdown of reliable sources:

Source Rerolls per Week Notes
Raids (6 raids total) 600 (100 each) Six raids, not five; reset weekly
Ultra Boss Shop (×3 shops) 1,500 One shop gives 100, others give 200 each
Featured Challenges 1,100 65 per challenge, 3 challenges daily = 220/day, ×5 days? (resets daily)
Extraction Mode (Spider‑Man) 40 per run (15 min) Can farm repeatedly for extra rerolls
Event Shops & Codes ~300–500 Seasonal codes and event claims
Total potential ~2,500–3,000 If you do everything

Pro tip: The fastest reroll farm is to complete one boss quest, then immediately do an extraction (end the game early). You still get rewards and have a chance at the boss.

Gold

Gold is plentiful – simply sell unwanted units and complete stages. No specific farm needed; it accumulates naturally.

Mastering the Extraction Game Mode

The extraction mode is the highlight of this update. The Spider‑Man version is far easier than the Joker extraction, so start there.

  • Team setup: Bring your best DPS units (Ichigo, Rukia) and supports (Fern). The Spider‑Man units you unlock will eventually carry you.
  • Strategy: Focus on completing the objectives quickly. Many players recommend playing with others for faster clears.
  • Rewards per run: 40 rerolls and a chance to drop Spider‑Man units.
Extraction Type Difficulty Key Rewards Recommended Units
Spider‑Man Moderate Spider‑Man, Venom, Iron‑Man synergies Ichigo, Rukia, Kimpachi
Joker High Joker unit Meta team (Spider‑Man trio)

The Spider‑Man trio (Spider‑Man, Venom, and Iron Man) have powerful synchro abilities when maxed – they can deal over a million damage each with bleed and burn effects. This makes them the most broken setup in the current meta.

Final Tips & Team Composition

If you want to thrive in the current meta, aim for the following end‑game team:

  • Main DPS: Ichigo (Rage) or Rukia (evolved)
  • Secondary DPS: Spider‑Man unit (or Joker if you can grind it)
  • Synchro slot: Pair Spider‑Man with Venom and Iron‑Man for the triple synergy
  • Support: Fern or any other buffer
  • Flex: Grammy – if you manage to pull the unrivaled unit, use it

Avoid: Persona units, summer capsule units, and most of the new mythics (except Rukia). The old Dragon‑Ball units are no longer top tier.

Remember that this universal tower defense z update guide is based on early community experiences. The meta may shift as more players test the new content. Keep an eye on forums and discord for future balance changes.
