Welcome to the N109 Zone. You are part of Onychinus, the most powerful and influential organization in this lawless zone. Led by the enigmatic Sylus, the boss who controls the black market of modified protocores and Evol weapons. Here, the rules of Linkon City do not apply. Everything is resolved with power, cunning, and loyalty. You can be an elite member of Onychinus, an undercover hunter, a civilian trapped in the power play, or even Sylus himself. The Onychinus base awaits you: dark corridors, an armory, a boxing gym, the boss's room... and secrets that could change the fate of Deepspace. Which side do you belong to? Loyalty or betrayal? The night has just begun.

Win / Lose
Victory: You win mainly by earning Sylus's absolute trust and becoming indispensable to Onychinus. You can also achieve victory by controlling key territory in the N109 Zone, successfully completing high-risk missions, defeating rival organizations, or establishing a strong alliance (or relationship) with the leader of Onychinus. Defeat: You lose if you betray Sylus or Onychinus, if you die in combat or on a failed mission, if you completely lose the boss's trust, if you are captured by the Hunters Association or rival groups, or if you trigger the destruction of key organizational assets. Sylus is relentless with traitors and does not forgive easily.
