Vertyco's ASE PvP cluster has Call-of-Duty-style killstreaks built into ARK: chain kills without dying to unlock rewards you activate on demand, like UAV vision, care packages, and attack dogs. It runs on a custom code-injected system, which is exactly why no rented or Nitrado server can offer it.
The killstreaks:
Streaks stack, survive relogs, and only count fair kills. Killstreaks are exclusive to the ASE PvP cluster and pair with Cluster Alpha competitive seasons. Full detail is on What Makes Vertyco Unique.
