Updates from the team
Your race is only the beginning. Weapons, spells, and gadgets complete the build. Experiment every match.
Four races. Four ways to fight. Select from Human, Elf, Orc, or Siphon, each with distinct mechanics, playstyles, and relationships to Aether. Your race defines how you move, engage, and bend the rules of the battlefield.
Your bloodline is your foundation for battle
Every race can wield every weapon, but strength and weight shape the tradeoff. Heavy weapons deliver devastating firepower but may slow less powerful races, while lighter weapons preserve speed and mobility.
Choose the weapon that completes your build
Use advanced technology to gather information, control space, support your team, or disrupt the enemy, and pair gadgets with your race and spells for combinations opponents may never see coming.
Intel, space control, support, and disruption
Gunplay alone won't win rounds. Every race has access to abilities spanning arcane magic to cutting-edge technology. Build your loadout, read the round, and master Aether to create a playstyle that's entirely your own.
How you combine them separates good from great
