Here's a new trailer from Trinium Wars, showing off PvE gameplay from the upcoming post-apocalyptic MMORPG and introducing the game's three-class system. This is set to launch in early access next week, and here's what you need to know about how classy this will be:

• Warrior: As two handed sword wielding masters of melee attacks, Warriors can take on several enemies at once. Although being very effective with melee attacks, Warriors are also equipped with a machine gun for ranged support. With heavy armor on, they are perfect tanks, nevertheless they can support allies with buffs and smaller heals as well.
• Ghost is an agile class, depending on quick attacks, stuns and debuffs. Equipped with claws and a machine gun, attacks are both based on long-range and close quarter combat. Ghosts can lay traps, make themselves invisible and even detect other invisible units. They are masters of the shadows and skilled in evading danger due to their light armor.
• Esper, the third class in Trinium Wars, uses range attack only. They can freely manipulate energies of nature and use diverse elemental powers. Esper possess powerful single-target or areal skills and also take the role of a health and status healer for party members. They supplement their weaker body with protective skills, summons and teleportation.

All three classes have different skillsets. Skills can be bought and upgraded at trainers for Tau, which is an inferior version of the precious Trinium. Each class can acquire an additional skillset called mechanic skill. The mechanic skillset consists of 10 base skills, which every class can learn, ranging from summoning machinery, setting up mines to mortar attacks, plus eight class exclusive skills. In contrast to normal skills, the mechanic skill can not be learned from a trainer but either be found as rare loot or crafted in the base building mode. The sheer amount of skills to choose from allow variations inside the three different classes. Together with the detailed character customization every player can create and progress their character to their own liking and set their own focus. Trinium Wars will be available via Steam Early Access 2nd of March 2016.
