The game

Control the sky, own the ground

Frontline Zero is a classic base-building RTS in the spirit of the great real-time strategy games of the 2000s: build, gather income from towns, industry and oil, and field a combined-arms force. Then the modern front line takes over. Cheap drones are deadly to anything left uncovered, jammers knock them out of the sky, and artillery reaches across the map. Every army has to answer one question first: what covers me from above?

Play Ukraine or Russia in skirmish battles against the AI, one against one or two against two, on maps drawn from real battles.

What sets it apart

The modern front line, in real time

01

Drones and jamming

FPV drones hunt armor and infantry; electronic warfare drops them out of the sky; fiber-optic drones fly straight through the jamming. Guns and missiles are the hard counter.

02

Fires and counter-fires

Mortars, howitzers and rocket artillery outrange everything on the ground, but they have to deploy to fire and give themselves away when they do. Shoot, then move.

03

The ground fights back

Trenches, dugouts, garrisoned buildings and minefields make defense cheap. Engineers and artillery are how a line gets cracked.

04

Two sides, two ways to fight

Ukraine plays precision, dispersion and adaptation; Russia plays mass, firepower and fortification. One readable set of buildings, two very different armies.

05

Air power

Air defense sites, attack helicopters, jets and long-range strikes. Knock out the enemy's air defense to open a window for your drones and aircraft.

06

Classic RTS clarity

Chunky, readable units, one-click orders, a sidebar to build from, team colors on everything, and units that answer in their own language.

Six battlegrounds

Maps from real battles

Each map is built around the ground that mattered: the airfield, the tower blocks, the steelworks, the river crossings. Play them in spring or winter, under sun or overcast.
