# Introduction

There are 2 types of progress bars:

* **Classic:** Only one mission is displayed on the bar at a given time, and the bar resets when the next mission begins.
* **Milestones:** All missions are displayed simultaneously along the bar. Players can see every reward ahead of them, including the final grand reward at the last mission.
