## New Progression Systems

### Challenges
A full challenge framework has been added to the game. Challenges can now track kills, weapon kills, headshots, objectives, extractions, deaths, loot boxes, coins spent, time survived, gas-related accomplishments, and special run conditions.

This system now powers long-term progression across both normal mode and challenge mode.

### Player Titles
Player titles are now unlockable through challenges.

Unlocked titles can be equipped from the Career menu and will appear on the player profile. Titles are also supported in leaderboard entries so players can show off their equipped title next to their name.

Locked titles appear as hidden entries until earned.

### Weapon Camos
Weapon camos are now part of the progression system.

Camos are unlocked through challenges and can be viewed from the new Camos tab in the Career menu. Camos show their unlock description, progress, locked/unlocked state, and preview image.

Camos can be equipped directly from the Career menu and apply to weapons without requiring duplicate weapon prefabs.

Prestige camos are also supported and display with special gold styling.

## Career & Leaderboards

Added a new dynamic leaderboard menu using the same visual style system as the Career menu.

Leaderboards now show player name, profile image, equipped title, and lifetime kills.

The Career menu now supports tabs for Career and Camos, with separate style controls for tab colors.

Added title selection dropdown to the Career profile.

Improved Career and Leaderboard layout controls, including separate sizing, padding, sprites, colors, fonts, sounds, and window titles.

Fixed profile/avatar border styling so Career and Leaderboards can use independent colors.

Fixed player names briefly appearing too small when Career or Leaderboards opened.

Fixed leaderboard row display issues.

## Unlock Notifications

Added unlock toast notifications for titles and camos.

Unlock notifications now work in both normal mode and challenge mode, include sound support, and can be tested with a debug key.

Fixed toast icon tinting so assigned icons keep their original colors.

Fixed unlock toast text clipping.

## Gameplay & Economy

Zombie kill coin rewards have been increased:
- Basic zombies now reward more coins.
- Infected zombies reward more.
- Dreadnaughts reward significantly more.

Objective and escape economy has been adjusted to better support longer runs and loot box usage.

Challenge mode helicopter escape pricing now changes based on gas ring phase, creating more meaningful timed escape decisions.

Normal mode helicopter escape pricing now scales more gradually with objective completion.

Clearance Sale has been changed from a flat discount to 50% off.

Loot box drops, weapons, attachments, and scorestreaks have had their floating height adjusted so they are easier to see and interact with.

## Gas Ring & Challenge Mode

Improved challenge mode gas behavior so the gas closes toward the final safe area more correctly.

The gas now starts as a rectangular boundary around the base and closes toward the final circular safe area.

Fixed issues where the gas could leave uncovered areas behind as it moved inward.

Fixed cases where players could stop taking gas damage incorrectly.

The gas warning indicator now turns red whenever the player is inside the gas, even if protected by a gas mask.

## Settings & Audio

Added a persistent settings system that carries between scenes.

Added volume controls for the game’s audio mixer groups, including master/global volume and configured music, UI, SFX, and voice channels.

Fixed mixer routing issues where UI volume could affect gameplay weapon audio.

Added close/refresh sound support for popup menus.

Settings menus can now be positioned differently depending on whether they are opened from the main menu or in-game.

## Main Menu & UI

Added random main menu quote/tagline support.

Improved quote positioning and ultrawide behavior.

Fixed cases where UI text or popup windows could clip on ultrawide displays.

Popup dim backgrounds now block clicks and hover sounds behind them, preventing players from interacting with main menu buttons while a popup is open.

Fixed main menu button hover/click detection being active outside the visible button area.

Improved loading screen routing before major scene transitions.

Added in-round kill counter UI support.

Added in-round objectives completed counter UI support.
