About
Dusk falls over the city. The sirens wail. Searchlights sweep the sky... and the bombers arrive.
Cielo Hostil is an anti-aircraft defense game where you control the cannon that protects the city. Hold your finger down and aim the flak, burst the bombs before they hit the rooftops and shoot down wave after wave of planes, helicopters and zeppelins.
AIM YOURSELF... OR LET THE CANNON FIRE ON ITS OWN
- Aiming by hand deals more damage and lets you burst bombs in mid-air.
- If you don't touch the screen, the cannon aims at the nearest plane by itself, though less accurately.
- Chain kills together to build streaks that multiply your coins.
A SKY FULL OF ENEMIES
- Fighters, bombers, zigzagging jets, zeppelins and squadrons in formation.
- The Phantom Wing, almost invisible: you'll only see it under the searchlights.
- Helicopters with tactics of their own: the Mosquito marks the city, the Wasp hovers in place and fires rockets, and the Mule carries explosives. Cut the cable before it reaches the center.
- Dive bombers, minelayers that drop mines by parachute, jammers that blind your auto-aim and tanker planes that repair the others.
- More than a dozen different enemies that show up little by little: there's always something new to discover.
5 UNIQUE BOSSES
Every five waves a boss appears with its own attack and its own weak point:
- Flying Fortress: carpets of bombs and turrets that shoot down your flak. Blow up its engines.
- Red Ace: a legendary triplane that dives and dodges. Catch it in a searchlight.
- Armored Zeppelin: heavily armored, with escorts and incendiary bombs.
- Prototype X: guided rockets and impossible bursts of speed.
- The Shadow: invisible outside the searchlights, with decoys and flares.
And once you beat them, they come back stronger.
EVERY WAVE IS DIFFERENT
Fog, storms that deflect your shots, full-moon nights and lightning raids. And now and then, an allied convoy brings supplies... unless you shoot it down yourself.
UPGRADE YOUR DEFENSE
- Spend your coins in the field workshop: every purchase makes the others more expensive, so choose wisely.
- Defeat a boss and pick a free reinforcement. From then on you can start a run right after it.
- Earn crystals and unlock permanent upgrades in the headquarters tree: more health, more damage, the Fury ability and guided missiles that launch from their own launchers.
- Customize your base and your cannon: twin anti-aircraft, quad rapid-fire or rocket launcher, each with its own shot and sound.
THERE'S ALWAYS A REASON TO COME BACK
- Daily missions and rewards for every day in a row you play.
- 16 achievements to earn.
- A war encyclopedia that fills in with every enemy you spot.
- Beat your record for waves survived.
MADE WITH CARE
Hand-drawn vector illustrations, a city that collapses and burns with every bomb, period music and sirens, and sunset lighting effects. It works offline, with no sign-up, and adapts to modest phones with its automatic quality mode.
