About

Celestrike

Read full description

They came to shut your black-budget satellite programme down. Something didn't smell right, so you took it rogue: the satellites, the stealth launch site, all of it. Now you spy on the world from orbit, fight a cold war nobody admits is happening, and chase the UFOs everyone says aren't there. Celestrike is a spy-satellite strategy game played on real orbits, over an Earth drawn from NASA imagery, with drifting cloud and city lights after dark. SPY Secret sites are invisible from orbit until you zoom in and hunt for them. Pick a satellite, pick a site, and collect intel every time it passes overhead. Collection carries on with the app closed. Sell the intel for credits, then spend them on better parts or another satellite. STRIKE Other satellites share your sky. Fly past one for a look, or fall in behind it and shadow it. Hold close and you steal its technology; hold at any range and you drain the data it has collected. Arm your satellites with mines, a railgun or EMPs and bring rivals down. Some targets fire back. INVESTIGATE Not everything up there is ours. UFOs circle faster than any orbit allows and answer to no registry. Your camera catches them as blurs at first; a better camera shows shapes nobody has on file. Plot your sightings and they lead you to alien bases hidden under open ocean and polar ice. Craft come down, sit on the ground for days, then leave: find one from orbit and send a recovery team to take what it leaves behind. Enough recovered hardware builds the TRB-01, a strike craft fast enough to catch a UFO in flight and bring it down in a real-time dogfight. Then send a team to collect the wreckage. Alien technology unlocks parts no human factory builds. EVERY MOVE COSTS Where a satellite flies decides what it can see and how often it comes back. Every manoeuvre burns propellant, and only a paid servicing flight puts any back. Imaging satellites need daylight, and a storm under the pass slows them down; signals satellites work at three in the morning, in any weather. You never need to know orbital mechanics: every option says what it costs and what it buys. BUILD YOUR FLEET Start with one satellite; your first finished site pays for a second. Three hulls, and every bay is an upgrade ladder researched from the intel you collect, so the targets you chase decide what you unlock. No level gates. Satellites, parts and propellant are only ever bought with credits the fleet earns. SKIP THE WAIT, IF YOU WANT TO One real minute is one game hour, and waiting always works. If you would rather not wait, an optional purchase sells packs of in-game hours that fast-forward the whole world: every satellite collects, every mission lands, every tank burns. You choose how many hours to spend each time, and the game never spends them for you. New campaigns start with 200 hours free. Single player. Fully offline: no account, no sign-in, no server, no ads, no tracking.

Verdict

The call

The clearest difference is in-app purchases: K2 Story at none against Celestrike's 3. Celestrike's advantage is ads (none vs shown) and update cadence (every 11 days vs every 4 months). On price and device support there is nothing between them.
