Update 6 introduces the Star Pass, a game-changing progression system that fundamentally alters how players earn rewards and progress through the game. This new feature provides structured long-term goals with exclusive, time-limited rewards that will never return.
Contents
The Star Pass operates on a mission-based progression system with three types of objectives:
Daily Missions: Refresh every 24 hours and provide consistent engagement opportunities Weekly Missions: Offer medium-term goals with substantial rewards Monthly Missions: Present challenging objectives with the most valuable prizes
As you complete missions, you earn Star Pass experience that levels up your pass. Each level unlocks increasingly valuable rewards, with the most prestigious rewards reserved for the highest tiers.
The most significant aspect of the Star Pass system is the introduction of exclusive units that will never return in future banners or events. According to developer confirmation, these units are truly limited, making them essential for both collectors and competitive players.
Key Star Pass Features:
The Portal System represents Update 6's most ambitious addition to end-game content, providing dedicated players with challenging new gameplay experiences and exclusive rewards.

A: No. The developers have explicitly confirmed that units obtained through the Star Pass system are exclusive and will never return in future banners or events. This makes them truly limited collectibles.
A: The Trait Pity System increases your odds of receiving higher-tier traits after multiple unsuccessful attempts. Each failed roll increases your pity counter, which boosts the probability of better traits on subsequent attempts, significantly reducing the RNG frustration.
A: Start with lower-tier portals to build currency and understand the modifier patterns. Keep multiple team compositions ready for different elemental combinations, and focus on one portal at a time since you can only have one active portal.
A: Yes, all ASTD X codes are case-sensitive and must be entered exactly as shown, typically in all capital letters. Double-check your entry before redeeming.
A: Flaming Tiger (Primal) should be your top priority due to its exclusive status and top-tier power. Blood Queen is also highly recommended for her meta-defining cleanse abilities that are essential for high-level content.
A: Code release frequency varies, but they typically appear during major updates, events, or when the game reaches milestones. Follow the official Twitter for the most up-to-date code releases.
A: Trading availability depends on how the Star Pass was obtained. Star Passes purchased with Robux are typically tradable, while those obtained through gameplay may have restrictions.
Mission Prioritization: Focus on daily missions first for consistent progress, then tackle weekly missions for larger rewards. Save monthly missions for when you have dedicated playtime.
Resource Management: Save premium currency for Star Pass levels that contain exclusive units rather than spending it on lower-tier rewards.
Team Synergy: Build teams specifically designed to complete Star Pass missions efficiently, rather than using your general-purpose teams.
Modifier Adaptation: Create multiple team compositions that excel under different elemental modifiers. Keep these teams ready for quick switching.
Currency Management: Focus on one portal type at a time to maximize currency efficiency rather than spreading resources across both portals.
Progression Planning: Use lower-tier portal runs to practice mechanics and build currency before attempting high-stakes Unbound runs.
Primal Priority: Invest resources in Flaming Tiger first, as the Primal rarity represents the long-term power ceiling.
