### 🐾 Collect & Upgrade Cat Heroes

AstroCats features a growing collection of **NFT cat heroes**, each with distinctive visual traits, classes, elements, and special abilities. Heroes are categorized by **rarity tiers** (Common → Mythic), and their combat performance directly influences your progression and earnings.

* **Summoning**: Acquire heroes through in-game summoning portals, event rewards, or secondary marketplace trading.
* **Leveling Up**: Use EXP and materials earned from battles to boost hero stats.
* **Fusion System**: Merge duplicate or lower-tier heroes to create stronger versions and unlock higher rarity classes.
* **Class Roles & Elements**: Strategically mix Tanks, DPS, Healers, and Supports with elemental affinities (Fire, Nature, Cosmic, etc.) to build powerful team synergies.
* **Equipment System**: Equip your heroes with weapons, armor, and accessories for stat enhancements and set bonuses.

Every hero is **on-chain**, allowing players to fully own, trade, or lease their digital assets.

### 💤 Idle Combat System

AstroCats is built around a **"play less, earn more"** model with a powerful idle system that ensures players earn rewards even when they’re offline.

* **Auto Battles**: Your team fights enemies automatically in real-time, even when you're not playing.
* **Reward Accumulation**: Log in at your convenience to collect EXP, gear, tokens, and other loot earned during idle periods.
* **Auto-Optimization**: Smart AI assigns your heroes to the best matchups based on their skills and formation.
* **Speed-Up Boosts**: Use in-game items or $ASTRO tokens to accelerate idle rewards and progression.

Perfect for both casual players and hardcore grinders, this system ensures no effort goes unrewarded.

## 🪙 On-Chain Economy

The game operates on **a nominal-token model** built for sustainability and long-term value creation:

Key Economic Features:

* **NFT Marketplace**: Trade heroes, gear, and items freely with other players.
* **Crafting & Burning Mechanisms**: Maintain token scarcity by burning $ASTRO in crafting, fusion, and gear upgrades.
* **Reward Distribution**: Players earn tokens through PvE battles, PvP tournaments, guild wars, and seasonal events.

All transactions are conducted on the **TRN Network**, ensuring lightning-fast speeds and negligible gas fees.

## 🧟 Zombie Invasion Mode

In this PvE mode, players must defend the galaxy from endless waves of undead space zombies.

* **Endless Wave Combat**: Survive increasing waves of enemies to test your team’s endurance and strategy.
* **Boss Zombies**: Face high-difficulty mini-bosses that drop rare loot, event currency, or NFT fragments.
* **Loot Tiers**: The longer your team survives, the better the rewards—tokens, relics, and exclusive gear.
* **Weekly Leaderboard**: Compete globally to secure top-tier rewards, limited NFTs, and recognition on the Galactic Leaderboard.

This mode rewards both passive players and strategic optimizers, ensuring wide participation.

## 🎯 Cross-Chain Expansion

AstroCats is being built with **Web3 interoperability** in mind to ensure long-term utility and asset portability.

* **Future Chain Integrations**: Planned support for popular chains such as Solana, BNB Chain, and Polygon to enable broader asset liquidity.
* **Cross-Chain Marketplace**: Buy, sell, and trade NFT heroes across chains without leaving the game.
* **Cross-Chain PvP (Planned)**: Engage in competitive tournaments where heroes from different chains face off in fair, skill-based arenas.
* **Multi-Wallet Support**: Connect multiple wallets and chains for flexible asset management.

Cross-chain functionality helps AstroCats reach a wider audience and increase NFT utility beyond the native TRN Network.
