RaiderZ is a Free-To-Play MMORPG with action-based gameplay. The player has the choice between five different combat styles - the Defender, the Berserker, the Sorcerer, the Cleric and the Assassin - to master the various challenges awaiting them. The story takes place in the Kingdom of Rendel, that has been struck by a severe meteorite crash five years ago and is still fighting against the effects of that crash, a seemingly unstoppable contamination. The player plays the role of a mercenary novice to become a heroic part of Rendel's history and to find a way to stop the contamination.

The Defender style is an expert for a combination of one-handed weapons and mighty shields. The Counterattack focus makes the defender capable of blocking the enemy's attacks and simultanously dealing severe damage to them. A defender's assortment of abilities is synonymous with surviving even the hardest of battles. Furthermore, the Defender is capable of creating hybrid talent trees, which is represented in learning other styles' active abilities, in case they are compatible with the equipped weapon. Thus the Defender is able to learn active talents from the Sorcerer and Cleric talent trees. However, passive talents are excluded from this limitation.

The Berserker style is focused on attacking and uses two-handed weapons. Despite the slow movements the attacks are capable of dealing great damage. As soon as the Berserker triggers its Outrage focus a far greater assortment of devastating attacks will be available. Furthermore, the Berserker is capable of creating hybrid talent trees, which is represented in learning other styles' active abilities, in case they are compatible with the equipped weapon. Thus the Berserker is able to learn active talents from the Cleric talent tree. However, passive talents are excluded from this limitation.

The Sorcerer style is known for its attack abilites which are based on the power of ice and fire magic. The weapon of choice is either a staff or a one-handed sword. By using the Awakening focus the Sorcerer is able to decrease the casting time of its attacks. Furthermore, the Sorcerer is capable of creating hybrid talent trees, which is represented in learning other styles' active abilities, in case they are compatible with the equipped weapon. Thus the Sorcerer is able to learn active talents from the Defender and the Cleric talent trees. However, passive talents are excluded from this limitation.

The Cleric style enables the players not only to heal, but also to use magical attack abilities. Most of the time the Cleric is using a staff, but is also able to wield maces and warhammers. Using the Possession focus will temporarily increase a Cleric's magic attack, in order to make the enemy meet their demise. Furthermore, the Cleric is capable of creating hybrid talent trees, which is represented in learning other styles' active abilities, in case they are compatible with the equipped weapon. Thus the Cleric is able to learn active talents from the Defender, the Berserker and the Sorcerer talent trees. However, passive talents are excluded from this limitation.

The Assassin style is an offensive attacker style, who uses two one-handed daggers. They are specialized in quick, strong attacks, that are enhanced by their natural critical strike chance. The Pursuit focus will increase an Assassin's movement speed after rolling, and it can be consumed to trigger the Finesse effect, which will increase the attack power. Regarding the ability to create hybrid talent trees the Assassin is an exception. They are not able to use active talents from other styles' talent trees but they still can profit from their passive talents.
