Hold the Rooftop. Survive the Next Wave.

Below you, the city is slowly disappearing into the night. Ahead of you, another enemy horde is pouring onto the rooftop.

Choose a character from one of many nations, pick up a weapon, and defend the last place on the skyscraper where anyone can still make a stand. Here, the nations are not fighting one another. Every character faces the same invading enemy. Your job is simple: stay alive, then get ready for an even deadlier wave.

Build Your Own Firepower

No two runs have to end with the same loadout.

Fight with blades, pistols, rifles, shotguns, machine guns, sniper rifles, RPGs, and an assortment of special equipment. Between battles, choose new abilities and gear: fire faster, hit harder, improve your chances of survival, or keep building around a favorite weapon.

There is no single correct build. Turning whatever you find into a force that can actually hold the rooftop is up to you.

One Fighter Is Not Enough? Hire a Few More.

As the battle continues, you can recruit mercenaries and equip them with weapons of their own.

They will acquire targets, fire, and reload alongside you. What begins as one lonely defender on a rooftop can grow into a wall of gunfire, explosions, and flying bullets—if you can keep the whole team alive long enough to see it happen.

The Hordes Never Stop

Runners, mutants, creatures that spawn offspring, and enormous bosses will keep changing the pressure on the battlefield.

Defeat enemies, collect experience, choose upgrades, visit the shop for new equipment, and return to the rooftop for another fight. The farther you go, the more dangerous the enemy numbers, strength, and combinations become. The early waves are only the beginning. The real challenge has no end.

Fight from Daylight into the Dead of Night

Time does not stop for the battle.

Daylight gradually gives way to dusk. The city lights come alive after dark, while muzzle flashes and explosions briefly illuminate the rooftop. Spent casings, enemy remains, and the marks left across the battlefield ensure that every defense leaves something behind.

Bring Your Own Fictional Ball into Battle

Alongside the existing cast, the customization system lets you create your own fictional ball, customize its appearance and weapons, and send it into the endless fight.

No matter where it comes from, everyone on the rooftop shares the same goal: stand together against the invaders and hold out until the very end.
