Your first big decision is your character's class. Each class plays very differently and focuses on different stats (strength, dexterity, intelligence, agility, and endurance).
The Velyrian colonists were not all originally trained in combat. Each colonist had a distinct role on the Homeworld. After the destruction of their ship, many of the remaining colonists chose to adapt their knowledge for battle. You have a choice between four base classes: the Soldiers, the Recruits, the Scientists and the Workers. Each class has its own advantages and disadvantages which affect your gameplay experience.
Project: Velyria employs a unique class advancement system where, as you level up, you will be presented with the opportunity to change your class. Each class advancement will grant you access to new and more powerful weapons and skills.
