About This Game

Twelve years ago, the sky split open.

Mist Gorge Basin is the last city with its lights still on. You are "Grey Falcon", the defense commander, with rooftop autocannon batteries, missile silos, AA turrets — and guardian mechs hidden underground. Every time the Rift opens, something new comes down: singing bell jellyfish, rock-hurling gravity shells, a thunderhead whale swimming through the clouds, carpet-bombing sky carriers that blot out the sun…

Shoot it down — then think about where it lands

Everything you destroy falls with real physics. Pop a bomber over downtown and its wreckage flattens your own towers. Lure it outside the city first — that's what a good commander does.

A fully destructible city

Buildings are chipped away block by block and collapse when they lose support. Burrowers dig through the dome at the city's edge and tunnel down to the Core Tower. When the upper city falls, the underground gun batteries hold the last line.

A 25-level campaign in 5 chapters

From the first swarm to the opening of the Sky Gate, follow Xiao Luo, Ke Yue, Shen Ruoqing and Bai Qiming as they uncover the secret of the Rift and the Core Tower. Every level has its own twist: overheating guns, a blackout night, escorting an evacuation train, holding out under the Sky Gate for the final countdown.

Prep and upgrades

Time stops between battles, and you only get three action points: repair buildings, draw tech cards, build turrets, deploy units — pick a few. With 18 tech cards, 3 guardian mechs, a railgun, a drone swarm and engineers, every run builds a different defense.
