What’s New in ASTD X Update 6?
Update 6 is packed with features that change how players progress, challenge themselves, and collect units. Here’s a detailed overview of the key additions.
1. The New Star Pass System
A new way to earn exclusive rewards has arrived. The Star Pass system offers a series of Daily, Weekly, and Monthly missions for players to complete. By leveling up the pass through mission progress, you can earn fantastic rewards.
Exclusive Units: Crucially, any units earned through the Star Pass are exclusive and will not return in the future, making them must-have items for collectors and meta-players alike.
2. The Challenging Portal System
This update introduces a complex new end-game mode: the Portal System.
How to Access: Portals can be purchased from the new Portal Shop, located near Serpent’s Way.
How It Works: Portals come in different tiers, from T1 to Unbound, each leading to powerful limited units. You can only have one active portal at a time. Each portal run features unique modifiers, including buffs and nerfs to specific elements, adding a layer of strategic depth.
Available Portals: The initial release includes two portals: the Patternine Portal and the Frost Moon Portal. Each has its own dedicated shop where you can spend currency earned from runs to purchase limited skins and units.
3. New Story Content and Trials
World 8 – Snowy Village: A new story chapter is available for players to conquer.
Trial 4: A new challenging trial has been added for end-game players.
NPC Quest: A new mission from the Shirtless Magician NPC is now live.
4. New Unit Rarities: Primal and Exclusive
Update 6 expands the game’s hierarchy with two new rarity tags:
Primal: A new top-tier rarity for heroes, equivalent to the “Unbound” tier.
Exclusive: A new tag given to limited 5-star units, denoting their special status.
5. Major Gameplay and Quality-of-Life (QoL) Improvements

Improved Unit UI: The unit inventory now has a scroll function, and upgrading a unit displays its health bar.
Optimized Lobby: The Castle Lobby has been optimized to reduce lag.

Frequently Asked Questions (FAQ)

A: No. The developers have confirmed that units obtained from the Star Pass are exclusive and will not return in future banners or events.
Q: How does the new Portal System work?

A: This is a new mechanic that increases your odds of receiving a higher-tier trait after several unsuccessful attempts, reducing the reliance on pure RNG.
Q: Are the new codes case-sensitive?
A: Yes, like most Roblox codes, they should be entered exactly as shown, in all capital letters.
Q: Which new unit is the best?
A: Units with the new Primal rarity, like Flaming Tiger, are typically designed to be among the most powerful in the game and are a high priority for players to obtain.
