Last Stand: Proving Ground
–
Join a unique game event and stop the monstrous Fatso at any cost!
The Proving Ground Files
The Wavebreaker
An enormous construct powered by Mirium energy. Once activated, it sends out devastating shockwaves—and triggers hordes of enemies to charge toward its signal.
The Fatso
A monstrous mechanical creature from the depths of the Mirium realm. Its only goal is to destroy the Wavebreaker. Hit its weak spots and bring it down before it reaches the center of the map.
Echo Tanks
Mutated combat machines driven by Mirium madness. Two new types join the fight—each with unpredictable behavior and new threats.
Babylon
Despite the growing threat, the Babylon Research Center remains active—testing new technologies under fire. If we succeed, we gain control. If we fail…well, failure isn't an option.
The Pied Piper
The enigmatic operator of the Wavebreaker. No one knows where he came from—but he understands all these otherworldly anomalies like no other. Watching him control the device is like watching a maestro conduct madness.
Mirium
A supernatural substance that defies all known laws of physics. First discovered after the catastrophic events in Mirny-13, Mirium fuels your Combat Abilities, but its secrets remain unsolved. All we know is the more you collect, the longer you survive.
Event Rules
Battle for Survival
Fight wave after wave of echo tanks in Tier VIII vehicles or rentals. Survive all five waves before time runs out.

Creates an energy shield that protects your vehicle from any damage except ramming, drowning, and impact for 7 s.
