Cross-platform modern warfare RTS.

A town is a wall to anything on wheels or tracks: the fight goes down its streets, and heavy shells bring the houses down around the guns. A river holds an army at its bridge until someone wades the ford, at half speed and under fire.

Battleships, destroyers, frigates, submarines and missile boats share one sea. A reef flat runs a hull aground, so the channels decide where a fleet can fight, and a submarine is found by sonar or not at all.

Flame tanks pour fire into the sandbags, thermobaric mortars lob over them and heavy tanks take the road while the light ones cross the ice. Every unit has an armor class it beats, and every unit page says which.

A silo needs a radar and a reactor, and only a veteran crew or a SAM site can shoot the warhead down. It flattens everything inside its ring, a town's houses included, and leaves the ground burning.

Rain takes a quarter of every unit's sight and snow a quarter of its speed on the ground. Only radar sees through the storm, and the bombers fly over all of it into the flak.

Landing craft run their ramps onto the beach, amphibious Gators swim ashore firing, and a battleship's broadside clears the dunes. Cargo planes land tanks behind the line and helicopters set engineers down anywhere.

A match starts at dawn and the day turns every 24 minutes. At night sight falls by 40 percent (radar excepted) and the headlights come on, and a frozen lake carries a column where no ship can follow.

Rocket batteries saturate a base from over the ridge; interceptor towers shoot rockets down, but never shells. High ground hides what stands on it from below and takes a quarter off every shot fired up at it.

Extractors on the deposits feed the war chest and power plants keep it moving. Overload the grid and production, defenses, mining and repairs all slow down.

The EMP is the silo's other warhead: where it comes down, every vehicle, ship and powered building goes dark for twelve seconds, guns silent and lamps out, and the column drives through a line that cannot answer.
