THE GAME / FORTRESS DEFENSE RTS

THE BASE IS YOURS.
SO IS THE FIGHT.

Build a working military outpost. Keep it alive under pressure.
Turn the aftermath of one wave into a plan for the next.

01 / INFRASTRUCTURE

Power the plan.

Generation and coverage determine what your base can sustain. Defenses, shields, production, research, and servicing draw on that network. A shortage changes which systems can keep working.

02 / COMBINED ARMS

Build a force.

Armored vehicles hold the line. Artillery reaches beyond it. Air defenses, aircraft, disruption, and carrier drones give you different answers as enemy formations evolve.

03 / RECOVERY

Keep it fighting.

Engineers salvage and repair. Wounded vehicles can withdraw to Repair Bays and return to their assignments. Aircraft cycle through Airfields to service and rearm.

THE CAMPAIGN / FIFTEEN WAVES

TAKE APART
THE IMPOSSIBLE.

The Titan brings shielding, multiple weapons, and an armored core. Target components to suppress its capabilities while keeping your base and support network alive.

The campaign culminates in this encounter. Victory opens the way to endless play, where the pressure continues to grow. Saving and between-wave autosaves let you return to a run.

Why recovery matters
TACTICAL CHOICES

MORE THAN
MORE FIREPOWER.

See the threat.

Sensors and reconnaissance matter. Concealed enemies must be detected; the Commander and minimap share the game’s visibility rules.

Invest under pressure.

Weapons, Engineering, Aviation, and Reverse Engineering compete for resources that could strengthen the perimeter right now.

Protect the support.

An Airfield, Repair Bay, or power source earns its place through the force it keeps operating. Infrastructure loss has tactical consequences.

Choose your authority.

Conventional controls and the optional local Commander work through the same game systems. Direct orders remain yours.

SELECTED PLAYER ROSTER / CURRENT DEVELOPMENT BUILD

A ROLE FOR
EVERY MACHINE.

Armored line combat

Viper Tank

A dependable center for the ground force. Combine it with support and specialist weapons rather than asking one chassis to solve every threat.

Precision & penetration

Railgun Tank

A specialist for deliberate target choice. Position it where precise fire can contribute while the rest of the force holds the approach.

Repair & salvage

Engineer

Keeps surviving vehicles useful and recovers materials from wreckage. Support work turns the space between waves into an opportunity.

Area bombardment

MLRS Thunder

Indirect fire for clustered threats. Its role complements the direct-fire line rather than replacing it.

Disruption

Tesla Tank

Electrical attacks add an answer to shields and disruption-sensitive threats. A different tool for a different defense.

Air defense

Spider AA

Mobile protection against aircraft and incoming missiles. Bring the right coverage when the threat moves overhead.

Air-to-ground attack

Cobra Gunship

Ground attack from a separate tactical domain. Its reach depends on protected Airfield production and service.

Committed attack runs

Wraith Bomber

Area bombing and EMP payloads reward planning. A released payload is a commitment, and the aircraft must return to rearm.

Flexible local support

Drone Carrier

Attack, interception, and repair flights work around the carrier. Their support has a radius, a replacement cost, and a vulnerable home.

Selected roles, not an exhaustive inventory. Research, equipment, and balance continue to evolve during development. Goliaths and the Titan belong to the enemy force.
