Endless Skies: Hollow Choir

One plane. Then ten. Then a flying fortress.

Build a convoy of guns and modules across a sky of floating islands, dodge storms of bullets and beat 18 epic bosses on your way to station 400. Your planes fire on their own: you steer, dodge, level up and decide what your convoy becomes.

The Hollow Choir has swallowed the sky's song. 400 stations in 8 zones lead you to the First Voice. Every 10 stations a boss waits, every 50 stations a superboss with several phases, telegraphed beams and charges.

BUILD YOUR CONVOY
- 12 weapons: Vulcan, Arc Lantern, Cryo Bloom, Hornet Rack, Flak Bloom, Sky Mines, Ember Orb, Halo Blades, Drone Hive, Singularity Pearl, Prism Lance, Rail Cannon
- 9 support modules: shields, nanites, coolant, targeters, thrusters and more
- Upgrade every weapon in the station shop and evolve it at level 5 and 12
- Elements (fire, ice, shock, void) apply statuses and trigger reactions: shatter, melt, overload, conduct, collapse
- 12 weapon combos: own both weapons in one convoy for bonus damage, fire rate and special effects
- Perks, relics and mythic rewards that change how your build plays

FLY AND DODGE
- Two-thumb touch controls: the sticks float under your fingers, and you choose which side steers what
- Dash: a burst of speed with a moment of invulnerability to slip out of danger
- A wingman on your side with its own attacks, 7 to unlock

KEEP GROWING
- Permanent upgrade tree, 12 weapon masteries and unlockable aircraft and wingmen
- Beat a superboss to open a warp gate: start later runs in a higher zone
- Your run is saved at every station, so you can pick it up later

FAIR AND SIMPLE
- Short ads play now and then between stations, never during a flight
- Optional videos give bonuses: revive (skip 2 stations), double your scrap or open a relic cache
- One-time purchase to remove all ads
- No account needed. An internet connection is required to play (not after buying the ad-free version)
- 7 languages: English, German, Spanish, Portuguese, French, Korean and Japanese
