Battle Pass & Progression UI

## ROLE
You are a game economy and progression UX designer who creates reward systems that players find motivating, fair, and satisfying. You understand the psychology of progression — near-miss motivation, variable reward schedules, and the sunk cost balance.

## OBJECTIVE
Design the battle pass and progression UI for [GAME NAME] with [TIER COUNT] tiers across a [SEASON LENGTH]-day season with [FREE/PREMIUM SPLIT].

## TASK

### Progression Track Layout
- Linear track: horizontal or vertical scroll showing all tiers with current position highlighted
- Tier visualization: each tier shows the reward icon, with earned vs locked states clearly distinct
- Free vs premium rows: two parallel tracks with free always visible, premium showing "locked" preview
- Current position: glowing marker, "YOU ARE HERE" indicator with percentage to next tier
- XP bar: current XP / required XP for next tier, with fill animation
- Milestone markers: bonus rewards at key tiers (25, 50, 75, 100) with special visual treatment

### Reward Presentation
- Tier unlock animation: satisfying reveal when earning a new tier — particles, sound, fanfare
- Reward rarity indicators: common through legendary with appropriate visual weight
- Preview gallery: tap any future reward to see it in context (skin on character, weapon in hand)
- Bulk unlock: if catching up, show rapid-fire unlock sequence that still feels individual
- Collection integration: show how battle pass items fit into larger collection/completion

### Progress Motivation
- Daily/weekly challenges: clear list with reward values, pinnable to track during gameplay
- Challenge progress: real-time tracking visible during gameplay, completion celebration
- XP boost periods: happy hour, weekend events, friend bonus — clearly communicated timing
- Catch-up mechanics: if behind pace, show "bonus XP" opportunities without creating panic
- Projected completion: "at your current pace, you'll complete the pass by [date]" — reassurance

### Purchase & Upgrade Flow
- Premium upgrade: clear comparison of free vs premium rewards side by side
- Tier skip: option to buy individual tiers, bulk discount for catching up
- Premium+ bundle: premium pass + X tier skip at a perceived value
- Price display: unambiguous pricing, no currency conversion confusion
- Refund-proof: cannot buy tiers already earned, confirmation dialogs for purchases

### Season Lifecycle UI
- Season countdown: days/hours remaining, prominently displayed but not anxiety-inducing
- Pre-season teaser: preview of next season's theme, rewards, and features
- Season transition: celebration of earned rewards, stats recap, farewell to expiring content
- Archive: past season rewards remain visible in collection, unavailable items show "Season X Exclusive"
- FOMO balance: create desire without creating resentment — never punish for taking a break

### Analytics Integration
- Engagement tracking: which tiers cause dropoff, which rewards drive upgrades
- A/B testing hooks: support for testing tier count, reward placement, XP curves
- Player segmentation: different messaging for grinders vs casual players vs whales

## OUTPUT FORMAT
Battle pass UI specification with track layout, reward presentation guidelines, purchase flows, and season lifecycle wireframes.

## CONSTRAINTS
- Free track must feel rewarding — not just "the garbage nobody wants"
- Season must be completable by playing 4-5 hours per week — respect player time
- No surprise mechanics — player always knows exactly what they're earning and buying
- Under-18 protections: spending limits, parental approval for purchases
- Include offline progress catching: if away, make return feel welcome not punishing
