The latest update for All Star Tower Defense X (ASTD X) has just dropped, and while this one is considered a “mini update” before the next major release, it still brings plenty of new content and system changes to keep players busy. From fresh 5-star units to a brand-new Unit Boost System, here’s a full breakdown of everything included in Update 5.5 before the next Update 6.
All Star Tower Defense X Update 5.5 Guide
1. New 5-Star Units
Update 5.5 introduces several new 5-star characters to the roster. Each of these comes with unique abilities and playstyles that players can test out:
- Soul The Boy
- Shield Master
- Cyber Psycho
- Pegasus Warrior
- Hybrid No.8
These units expand the current lineup and provide more flexibility for different team compositions.
2. Item Dismantle & Conversion System
A new system has been added that allows players to break down or convert certain items into Gold. This feature is especially useful for managing your inventory and maximizing value from items you may not need.
Recipes included in this update:
- Convert Skill Orb II → Skill Orb I
- Convert Rainbow Ghost III → Rainbow Ghost II
- Convert Rainbow Ghost II → Rainbow Ghost I
This gives players more control over resource management and crafting.
3. Unit Boost System
One of the biggest changes in Update 5.5 is the Unit Boost System, a mechanic that allows specific units to provide reward buffs (similar to cards) or extra damage in certain stages.
Currently, the Unit Boost System is active in:
- Trial 1
- Trial 2
- Trial 3 (Arc 1–3)
Expect more stages to support this system in future updates.
4. Stun Changes
To improve game balance, stun mechanics have been adjusted across the board:
- All set stun kills reduced to 15 seconds.
- Instant kill stuns have been completely removed.
- Global unit stun timer reduced from 120 seconds → 15 seconds.
These changes make battles more strategic and less reliant on stun-based tactics.
All Bug Fixes & Adjustments
This update also focuses heavily on fixing long-standing bugs and improving stability:
- Fixed Infinite Food Map Event Contract rewards not tracking.
- Fixed Spiral Pilot SPA values.
- Fixed issues with Brano Shirt, Cioclatta model, and Secco model.
- Fixed random units incorrectly appearing in the Unit Index.
