# Campaign The Campaign is a **stable and guaranteed way** to earn ZTD tokens in PvE mode for **24 months** after the mode is launched - rewards are allocated from the **Play-to-Earn token pool**. Complete levels, liberate sectors from zombies, and earn rewards for every victory. The better your performance - the more you earn. ### ⭐ Reward System Rewards are based on star ratings: * ⭐⭐⭐ **100% wall HP** → 100% of the reward * ⭐⭐ **99% to 50% wall HP** → 50% of the reward * ⭐ **49% to 1% wall HP** → 25% of the reward * ❌ **Defeat** → 0 tokens ### ⚠️ Important Rules * Each level reward is granted **only once** * If you first complete a level with 1 star and later improve to 3 stars - you'll receive the **difference** for the additional stars * After unlocking the next zone, you have **24 hours** to finish the current level and claim the reward - after that, it expires ### ✅ How It Works * Rewards are paid from the **Play-to-Earn pool** (42%) * Token rewards depend on the **number of stars earned** * Improve your performance - **earn more** * Each reward can only be **claimed once** The Campaign is your chance to **seize more sectors** and earn to the max! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
