# Story Mode (PVE)

**Story Mode** is the narrative-driven part of RoboHero, where players conquer levels to unravel the story of the RoboHero universe. This mode challenges players to progress through 6 sequentially arranged worlds, each with its unique environment and set of challenges:

* [**Void (Tutorial)**](/robohero-wiki/command-center/game-world/enviroments/void.md)
* [**Desert**](/robohero-wiki/command-center/game-world/enviroments/desert.md)
* [**Swamp**](/robohero-wiki/command-center/game-world/enviroments/swamp.md)
* [**Mountain**](/robohero-wiki/command-center/game-world/enviroments/mountains.md)
* [**City**](/robohero-wiki/command-center/game-world/enviroments/city.md)
* [**Jungle**](/robohero-wiki/command-center/game-world/enviroments/jungle.md)

Each world comprises 30 levels, with every level requiring the completion of a specific mission to advance. The 30th mission in each world is a special mission or a boss fight, presenting a higher difficulty level than standard missions. Successfully completing the 30th mission unlocks the next world.

### ⚡**Energy Requirements:**

* The first attempt at any mission consumes 1 energy.
* Subsequent attempts at the same mission cost 2 energy.
* Special missions and boss fights consistently require 3 energy.
* Without energy, players cannot engage in PVE battles.

### ⚔️**Opponents:** 

In Story Mode, the adversary is always an AI-controlled robot, with its type and kind dictated by the game's storyline. As players progress, enemies become increasingly challenging, featuring higher base stats and controlled by more advanced AI.

### 🏆**Rewards**

The primary rewards for progressing and completing missions in PVE mode include experience points ([EXP)](/robohero-wiki/command-center/robots/leveling-up/exp-points.md) for both the robot and player account, ASH, and items of lower quality. 

Boss fights and special missions offer the chance to obtain a larger quantity of the aforementioned assets and, on rare occasions, crystals and higher-quality items.
