ABOUT THE FULL GAME

THE DEAD ARE RAINING FROM THE SKY

Defend a neon cyberpunk district as infected rain from a breached corporate lab. Skyscraper Security: Zombie Rain is a fast first-person action roguelike where survival means more than keeping yourself alive.

Intercept falling threats, protect humans, and strengthen your defenses through 15 escalating waves, culminating in a confrontation with the Scraper.

BUILD YOUR DEFENDER

All four Defender classes are available from the start. Choose the weapon and fighting style that suit your approach:

• Skyguard: Control the airspace with a stable, long-range rifle.
• Breacher: Crush close-range ground threats with a powerful shotgun.
• Deadeye: Line up precise hand cannon shots and pierce through infected.
• Ronin: Wield a cyber-katana, chain close-range strikes, and launch into an execution charge during Focus.

Each class begins with its own combat doctrine. Reach Wave 8 with a class to unlock its alternate doctrine for future deployments, bringing the full arsenal to eight distinct doctrines.

Combine Level-Up cards and System Shop upgrades between waves to shape your build. Rare Recovered Tech grants a free upgrade for the current run.

PROTECT THE RESCUE GRID

Your four rescue drones move the Rescue Grid automatically to catch falling humans. Collect the SS Coins earned from rescues and spend them in the System Shop on equipment, rescue drones, and district repairs.

Defeated infected drop Bio-Samples. Collect enough to fill your XP bar and level up. Each level grants one SS Token to spend on Level-Up upgrades between waves. Later levels require more samples.

Your level, currencies, and purchased upgrades last for the current run. Unlocked doctrines and difficulty remain available for future runs.

BEND TIME. RETURN FIRE.

Hold Focus to slow the world with bullet time, line up attacks, and regain control when threats surround you. Attack during Focus to unleash your doctrine’s special attack, spending extra Focus in addition to its steady drain.

Dash to reposition and parry hostile projectiles with your own attacks. Both gunfire and katana strikes can intercept incoming fire.

SURVIVE THE SHIFT

Face increasingly varied infected whose abilities create dangerous synergies, including later-wave Brutes and Jumpers. Choose your targets carefully and protect the grid: infected that land in it become Overcharged. Certain enemy projectiles can Overcharge them too.

Fight through Wave 15 and defeat the Scraper to unlock Hard mode. Earn alternate doctrines, pursue in-game achievements, and return with new ways to approach the next deployment.

MAKE YOUR CALLSIGN KNOWN

Compare your performance on global leaderboards and follow worldwide Defender statistics.

Enable optional Online Records to publish completed-run scores, achievement unlocks, and anonymous Defender death reports. Your local progression and in-game achievements remain available with online publishing turned off.
