Command has authorized the Weapon Refine System, and the mind behind it is Riley, daughter of the Mechanic. And she just changed the way you upgrade weapons forever.
The Weapon Refine System is an advanced upgrade path for gunship and troop weapons. Weapons can gain Refine Marks (MK1 to MK6), represented as gold stars, each unlocking performance enhancements or tactical bonuses.
The further you refine, the deadlier it gets.
Want the full system breakdown? You’ll only find it in one place: our official ZGS Discord.
In a world crumbling under the weight of the undead, only those who evolve endure. Get ready, Airmen. The future of firepower is in your hands.[/p]

Solstice Z
Attention, Airmen,
The summer sun might be blazin, but the battlefield just got hotter.
Solstice Z is live with new Objectives that put your tactical skills to the test. Fresh challenges. Fresh rewards. No room for hesitation.
And to help you cut through the chaos? Meet the ZPU-1, a heavy-duty standard weapon designed to mow down undead swarms with ruthless efficiency. Every 3rd shot builds Residual Heat, until it overheats and unleashes a cataclysmic finisher.
The days are long. The zombies are many. Make every shot count.
Introducing the ZPU-1
[p][/p][p]ZPU-1 Standard Weapon: WHEN THEY RUN, YOU HOLD.
Attention, Airmen!
They don’t shamble anymore. They sprint. They swarm. By the time you reload, it’s too late.
The ZPU-1 LIGHT CANNON was purpose-built for one role: breaking fast-moving zombie packs before they can overrun defensive lines. Its firing system is tuned for sustained pressure and controlled bursts, exactly what today’s battlefields demand.
Infinite ammo: never stop firing. You can’t afford to.
Overheat system: every 3rd shot builds 10% residual heat, heat that won’t cool down passively.
When the weapon nears overheat, its final purge shot converts that built-up heat into a devastating blast of amplified damage and expanded radius.
Deploy the ZPU-1 LIGHT CANNON now. Because the fast ones are coming.[/p]
Introducing the A70B BZ "Blightzone"

Airstrike
Attention, Airmen!
Civilization is falling. Survivors are trapped. Your gunship is their last hope!
Operation Airstrike Sanctuary is underway. Civilians await extraction, but the ground is overrun:
Shamblers swarm from every angle. Hellhounds streak ahead, their deaths fueling the horde’s speed. Bloaters detonate with vicious intent. Regenerating Titans restore the ranks as fast as you thin them. Wreckers bring ruin to defenses. Hellbeasts rally their kin to unholy speeds. The Howler freezes survivors and blinds your vision. The Kindred splits into a swarm at half-strength. Grimeye decimates the field, rising untouchable before summoning an unstoppable flood.
Only overwhelming firepower will turn the tide. The call has gone out, answer it. Rain steel from the heavens.

Endless Hunger
Attention, Airmen!
Our radar has spotted a swarm of small but fast zombies flooding the base from all sides. The horde appears endless, and tension escalates with each passing moment.
On the horizon, the imposing Canis Mortis emerges as the supreme foe, commanding countless Starving Hellbeasts.
Your window is closing, hold the line or lose it all. Take the fight to the zombies before they take the base.

New Sanctuary Event: Hollow Glen
Attention Airmen,
Something has awoken in Hollow Glen. Anomalous activity has surged, and every recon squad sent in... hasn’t come back out. Survivors speak of Ravenous Shamblers that erupt into motion the moment they’re wounded, regenerating as they charge. Resilient Wreckers now halt mid-combat, shrugging off damage like they’ve forgotten how to die.
The ground trembles to the rhythm of the Deathchanters—when slain, they explode, dealing devastating damage to both zombies and survivors. Palesayers slip among the hordes, accelerating every rotten footfall toward your lines. And from the heart of the Grove, Hellmasters emerge—immune to napalm, spawning endless waves of twisted, fireproof Hellhounds and Hellbeasts.
But it’s not the Grove you need to fear. It’s what walks beyond it.
The Hollow King has risen. A towering Titan whose arms stretch farther than any gunner has ever seen. If it reaches you… you won’t get a second shot.
Eight years ago, zombies flooded the streets. Chaos reigned. But from the skies, the gunships roared. Humanity fought back — and from the cockpit of the AC-130, you answered the call. You’ve delivered fire, fury, and salvation across the wasteland. And because of you, civilization still stands.

The mission never ends. The skies are still ours. Here’s to eight years of fire, flight, and fighting zombies — and to many more!
Introducing the Flak 18-36
Attention, Airmen!
In times like these, when zombies push harder with every wave, when survivors are cornered and outposts burn under pressure, there’s no room for hesitation.
In an era where the dead don’t stay dead, humanity turns to the past for salvation. The Flak 18-36 is a monument to firepower—a relic reborn to end the plague.
It launches a projectile that pulls nearby zombies into a deadly vortex before detonating a second time with an even bigger explosive force. Scattered enemies become a single target. One shot. Two impacts. Total devastation.
The Flak 18-36 uses an overheat-based system and infinite ammo, giving you the freedom to hold fire.
Keep the skies hot. Keep the zombies off the ground.
