Recon / Offense
ECC: REDLINE Athlete
Sirius, known as 天狼 (Tianlang) in Chinese material and Ace in early leaks, specializes in tracking enemies and applying pressure through autonomous equipment.
His abilities combine a mechanical attack dog, a tracking drone, and bonus firearm damage against targets detected by those devices.
The kit
Core Ability
Sirius summons a mechanical hound called Howler.
Howler automatically detects nearby opponents, pursues them, and attacks.
Howler's attack damage was listed at 12 damage per second in the playtest build tested by our team.
Because Howler operates independently, Sirius can pressure an enemy while continuing to use his own weapon.
Tactical Ability
Sirius deploys a tracking drone called Patrol Bee.
The drone searches for previously unscanned opponents near its deployment location. Once it detects a target, it locks on, reveals enemy information to the squad, and can explode.
This makes the drone useful for checking dangerous areas or finding enemies before committing to a fight.
Passive Skill
Sirius deals additional firearm damage to enemies currently locked onto by Howler or Patrol Bee.
This creates a direct connection between his detection equipment and offensive potential.
Sirius is particularly useful when a squad needs information before attacking.
His drone can help identify enemy positions, while Howler forces opponents to respond to an additional source of damage.
Instead of treating these tools as independent abilities, players can use them together: deploy tracking equipment, identify the target, then take advantage of Coordinate Assault.
The important limitation is that his passive depends on enemies being tracked by his equipment. It should not be treated as a permanent damage bonus against every opponent.
